    Vapor Barrier behind new door panels?

    Thanks for the response. Last time I did one I remover using some sort of weatherstrip sealant - I’ll need to look into that butyl tape.

    Vapor Barrier behind new door panels?

    Hi all. I have a 1981 C10 Silverado. Ordered new reproduction door panels that should be arriving early next year. When I messed with door panels in the past there was always a plastic vapor barrier between the panel and the door. There currently is no sign of one on this truck, and the door...

    Question about center grilles - 81-87

    Is this the component that the grille would mount to? (LMC calls it a “lower grille panel). https://www.usa1industries.com/1983-87-square-body-chevy-gmc-truck-front-bumper-to-grille-panel/

    Question about center grilles - 81-87

    Ha. I had to to exactly that when the center flange snapped off, but no suitable place at the edges. Maybe looking at it again after a good night’s sleep will shake something loose. I could probably make some supports out of stiff wire. It is very well secured at the top so it won’t need much...

    BTW - before and after pics. To my eye it is a huge improvement.

    High horn not working on a 1981 C10 Silverado

    The horn saga is over for now. I found one off of a ‘76 that mounted in yet another way I had never seen before - but the bracket was the same as mine, only reversed. I tried to find somebody who was willing to cut the bracket and weld it back on reversed but no shop will do anything for less...

    Question about center grilles - 81-87

    Yep - you are exactly right and I spoke too soon. The top secures nicely and the center screw on the bottom fits nicely, but there are two flanges on either side of the bottom are unsupported. So you are saying that these attach to the splash guard and not the headlight bezels? Yes, I’d like...

    Question about center grilles - 81-87

    Final answer: an ‘87 grille fits in my ‘81 C10. Have to remove the headlight bezels to get it in and then replace, but that’s the only thing about it.

    Question about center grilles - 81-87

    That’s my next option if I don’t come up with a grille this trip.

    Question about center grilles - 81-87

    OK, that’s interesting and good to know. Hopefully the seller has those too, if needed. He’s parting out three trucks all in the same year range, so chances are good has them and the ones currently on my truck are not in the best shape anyway. Thanks.

    Question about center grilles - 81-87

    I did the same search in LMC, USA-1 and other sites but I’m not convinced based on that evidence alone. I’m hoping somebody has direct experience. I’m heading out there tomorrow regardless to pick up a horn, so will have my answer soon. Would just be nice to know before I go so I can better...

    Question about center grilles - 81-87

    I have a 1981 C10 Silverado with dual headlights and one of those 1980’s JC Whitney-style billet center grilles that I’d dearly love to replace with anything more stock looking. I found a decent stock C10 center grille about an hour away from me off of a 1987 truck (photo below). Will it fit...

    Same horns all years?

    Good news is that I found a horn about an hour away and am going to pick it up tomorrow. At 8mpg, the gas is going to cost me more than the horn, but he might also have a grille that fits so Incan finally get rid of that gawdawful billet grille.

    Blower Issue

    Just wanted to get this out there in case anybody else comes across this problem. Originally the blower on my 1981 C10 Silverado would only work on the first three speeds and never on high. I heard that this often is because of the high speed blower cutout relay being bad. Without starting the...

    High horn not working on a 1981 C10 Silverado

    Yep - gave it a good try. Soaked it in aerokroil for over a day, emptied it and then tapped it progressively harder - checking continuity and testing with power between steps - until I was dropping it on the floor. It never came back to life. It's dead. Bummer.

    I have nothing to lose so I’ll give her a try and let you know.

    Same horns all years?

    I just got back from a local junk yard. They had a 1976 step side that had dual horns. Both are located on the drivers side, the low note is mounted exactly the same as it is on my 81 C10 and the other is mounted at 90 degrees right next to it - same high note unit but no bracket. So I have my...

    Same horns all years?

    Hi all - I’m going through Facebook marketplace ads trying to find a replacement high note horn. Does anybody know if they used the same horns for all years, 1973-1987? I know not all trim levels had dual horns, but it would save me time if it turned out that they used the same Delco Remy horns...

    High horn not working on a 1981 C10 Silverado

    I heard about that, but if I don’t have continuity I’m guessing that the coil is busted, so no way I’m getting current to pass.

    High horn not working on a 1981 C10 Silverado

    Don’t bother if it puts you to any trouble. I believe they’ll work just from what you told me. Also - and I’m kicking myself for not thinking of this - somebody put me on to Facebook Marketplace and I can now see that there are people parting out square bodies all over the place and it shouldn’t...

    High horn not working on a 1981 C10 Silverado

    I don’t think so. I’m pretty sure at least in 1981 that it was associated with the trim level.

    High horn not working on a 1981 C10 Silverado

    Yeah on the coil. I saw a YouTube video where a guy rebuilt his, but it wouldn’t work if the coil was shot. And thanks for the info on the LMC unit - I suspected it might not be a clean fit. Did you just have to bend the brackets they provided, or did you have to fabricate your own brackets...

    High horn not working on a 1981 C10 Silverado

    Didn’t expect to find one for free. Don’t know Ted, although University Place would be a lot easier to get to than Battle Ground. I have a question out to USA-1 Industries. Would happily buy theirs for $40 but would like to know how much trouble it will be to adapt. They don’t show any pics of...

    Good point, and I have his contact info. I wonder if he ships. Thanks.

    High horn not working on a 1981 C10 Silverado

    Hi all - the high horn (A note) on the passenger side does not work. The wire that feeds it is passing power, but no buzz, no click - nothing. I pulled the unit and tried hooking it up directly to the battery with no result. Did a continuity test and found that there was no continuity. Did the...
