    Terrible Smell from the Heater Vents

    Good idea. I used something like it for my custom window covers. Wish I'd thought to stick the rest under the front seat carpet. The rig does get awful hot. The new muffler (put in by POs) ticks audibly during cool down after driving a while. I had the radiator rodded, so I'm not worried about the engine so much, but it's pretty toasty under the cab.

    I WIN !!!! And it only took me four months to figure it out. oh well. The POs left a plastic caddy between the seats. On hot days it would heat up - and stink. When the truck ran for long enough to get hot, it would heat from beneath - and stink. The vents where it smelled the strongest - were right above it. I used a hair dryer (had to borrow one, don't own such a thing) to heat it up and yuppity yup yup that was the smell. So cooking plastic. Yum. Bet I lost a few brain cells on that one. Thank you all for your suggestions. And now I know how to take apart the dash (and put it back together) and how to fix the squeak in the steering.

    Terrible Smell from the Heater Vents

    Lo and behold, a new clue. I haven't gone anywhere for five days and haven't smelled The Smell for at least 2 weeks. Today the temp got up to about 66 with the sun shining down hard on the dash and hood. The smell came back to the point where I have to open the windows to breathe. Strongest from the right center vent. What would do this????!!!!!! There's nothing to see!!! Ambient heat triggers it and you don't have to drive to get it going.
  4. Hey Tim, don't give up. If you can expand your range into WA and OR, there are tons of RVs up there - got to watch out for the water damage though. I saw a beautifully maintained Sunrader near Portland but he wanted $10K for it. I could pass his info to you if you would like to see if he has come down in price. I had over a dozen rigs on my list (check Santa Barbara) and saw half of them before finding one in San Bernardino. It was a bit weird. They were asking 8k, I said I could only pay 5k, and they said they would take 4k. I think they were tired of tire kickers and paying the storage fee. I wasted no time running down there to pick it up. In retrospect considering what I've had to do - and still have to do to the Dolphin - I think 4 was a fair price. So it can be done. Maybe find a polite and respectful way to let them know what kind of cash you can offer that doesn't waste their time but gives them an option to reconsider their price? Also, like boats and houses, RV purchases are emotional, not rational purchases. The POs of my Dolphin had a need to be happy with the person who bought their rig - as I did when I sold my boat. So don't discount the possibility that you will be the right "fit" for the purchase. Nothing ventured, nothing gained, right? Also, thanks to the wildfires, SoCal is a lousy place to look for rigs right now. RVs were getting snapped up by people desperate for somewhere to live after that, and I'm guessing the market is thin now.

    Terrible Smell from the Heater Vents

    Well, good to know about the quick evaporation on those chemicals. This has been a problem since December when I had work done in Oxnard. I asked the mechanic what he sprayed in there and he said, "whatever it was it won't kill you - I'm still alive." Not encouraging. I don't believe he hot-dipped anything. We did spray the EFI cover and the heat shield with silver high heat rustoleum, but I would have thought after two months that would be long gone. Because the smell was intermittent, like all of the other symptoms in this rig, the source has been hard to pin down. I have a pretty sensitive nose and consider it a good diagnostic tool - as long as I can identify the smell. The first smell that came out of the heater vent (in October) was a distinct crayon wax smell. Very nostalgic, and possibly Blue Green, but maybe Green Blue. At any rate, that smell has gone away and I found no melted crayola in the dash, sad to say. Yesterday I drove to the bustling metropolis of Belen - about an hour and a half each way with a few inclines. I ran the heater part way, and also the fan on cool. There was zero smell before, during, or after. The outside temp got up to 70 (it has been in the 20 - 40 degree range), so the engine definitely got warm. I smelled a faint bit of antifreeze as I got out of the vehicle, but no drips anywhere. I can't believe that anything I did when I took the dash apart made the smell go away. Befuddling. So until I get any more stinky clues, this thread has tapered to a close. If it aint broke, don't fix it. So I'll turn back to the computer codes 4&5 that continue to flash. But that's a different forum category...

    Terrible Smell from the Heater Vents

    I almost got on Car Talk once with a Plymouth Colt Vista problem... But I'm definitely stumpin' the chumps here, because it ain't coolant. I believe it is something that has been added - like brake cleaner - where it doesn't belong. I'll keep you posted the next time I get a whiff. And I'll try to be more specific about the particular notes and bouquet of the wretched stench. Maybe we could introduce scratch n sniff to the forum?

    Germs, by definition, have some biological source. I am quite clear that the smell is a chemical that is man-made and probably is designed to kill things itself. So, until there is Smellivision adapted to this forum, you're all going to have to believe me, it's not a germ, mold, mouse, flora or fauna, rot, or anything else that is, was once, or could be alive.

    The idea is not to replace or mask one nasty smell with another. It's to find the source of the original nasty smell and eliminate it.

    Terrible Smell from the Heater Vents

    It wasn't coming from the tool bag. My snoot detected it coming from the center vents and around the steering column. It has faded. I have to wait for it to reappear to open up the dash again. Next time with more confidence and therefore FASTER

    Terrible Smell from the Heater Vents

    I took apart the dash and stared at the duct work for a couple of days. Greased up that horn contact continuation doohickey and fooled around with the radio. Then I put it back together, afraid if I waited too long I would forget how it goes. In that time the smell went away so much I couldn't sniff out a location for it. Before the smell disappeared it was strongest in the center vents and around the steering column. Another clue, possibly unrelated, is that when starting the engine and revving the accelerator in place, there's a gurgle in the center vents - only when revving.

    Ok. Perhaps I am not being descriptive enough. The blower works great. The heat works great. The heat DOES NOT smell. It's coming from in there but is not heater related - unless someone left a can of brake cleaner in there. I can 100% guarantee you this has nothing to do with mice. This is a man-made chemical substance. I knows from meeces. This 'aint natural. The sun is shining down on the dash right now. I haven't run the vehicle or the blower in four days. I can smell the chemical. Looks like I have to go in just to prove it's not mice. Rats. Pun intended.
  13. 86 Dolphin 67,000 mi. Wretched smell coming from heater vent - for about 1500 miles now. Sometimes so bad I have to close the vents and open the windows so we don't asphyxiate. First off, no, it's not coolant. I know that smell very well and that doesn't grab your tonsils and threaten to choke the life out of you. Only happens when engine hot Possibly only happens when heater has been used Much stronger when on recycled air setting Super strong after the vehicle is stopped Lingers for days in the seat area Definitely coming from the vents ( I thought there was something in my toolbag on the passenger floor, but I moved it) Is not dissipating with time First smell to come out of heater vent was a sweet crayon smell Then came this Brake fluid meets WD 40 meets Round Up toxic nasty stink I have looked at the videos of dash removal and the 40 different bits and bobs stuck under there. Am intimidated but can't think of how else to find the culprit without setting eyes on the leak / pool / dead alien rotting under the dash. Not sure I want to know Has anyone else had this problem? This is a Car Talk problem for sure.

    Oxidation of fiberglass on Sunrader

    Yes, another option for applying the oxalic acid. It comes in a spray bottle. If you spray it through the screen they provide, it foams. Need a photo of the bottle? Got it at Home Depot.

    Oxidation of fiberglass on Sunrader

    The barkeep and Zep combo is excellent. I've been using the foam spray (with gloves). Plus elbow grease. Huge difference. The Zep doesn't make the surface shiny despite the "wet look" promise on the label. It's more of a waxed, protected look. You don't see the shiny fiberglass fibers anymore. It's smooth and sealed and does not collect dust as much because the nooks and crannies have been filled. I have been using an old toothbrush on the caulking. A bonus to the up close up cleaning is that I can discover the places where I need to repair or bolster.
