Just tackled this before installing interior. I done the 9" rear end, body bushings, ac box rebuild, dash, floor shifter and now climate control rebuild, from your videos. Thanks.
My Ac won't blow at the top. Can you tell me the problem? Which part on mine is broken?
I just started watching your videos. They are great!! I have an 1987 El Camino. My heater controls came with the blue and red stripe on it
Hutch, just stumbled across this video. Couldn't ask for a better tutorial for fixing these control units. Great info!
Thanks just got mine out now I know
Great job great video was big help thanks man
Great video, thanks!
Where is the bulb located? Thanks
I'm inspired to investigate my 81 control …. the fan switch stopped working, so I hardwired full power to the fan motor to get heat in winter…. I also bypassed the hot water valve – I have to move the radiator hose to ON in winter, or total bypass in summer :0) Got doubts about my vacuum system too. The switch switch does not move well. Maybe I have the "no ball" style switch. I have to take a walk through the wrecker and see what I can find
I totally understand why folks are getting into these G bodies: the 60s "hotrods" are all high priced "collector" items now. Common folk want something they can "fix" (or break) themselves, cheap parts in wrecking yards. Now that is even getting rare. Mine came with a Buick V6, but I knew they also had V8 which would fit, even the 455 big blocks with minor mods (had to weld on a new engine mount to the rear crossmember and get the dreveshaft cur/balanced. Really great to see all the support from parts suppliers, and useful online presentations, thanks to people like you..
My hodge-podged 79 GM unit…mounted on a Dodge M500 Frame, all driven w/ 440/A727 drive train, all in a 1980 Fleetwood RV, E-25 Package equipped,, well it came as a "Some Assembly Required" deal 😉
My issue is the 7 "Teats" coming out the back and why in the world can't I find a diagram for proper what vacuum line to what teat placement anywhere….found a few for the typical round pattern, which also usually is accompanied with these mounted on a pre-fit plastic ring as to plug all vacuum lines in @ once 😉
and even more concerning is that there's only 4 vacuum lines (all 1 color, BLACK) to put on said teat's, and should I block off the remaining 3 teats….or start looking for different vacuum depend devices with no lines on them?. I did sort out which was my suck source by of course, starting the engine… guessing the other 3 here, one is for defrost flap other is for fresh/recircl and 3rd for heater core??? But that'll be the easy part, I just don't know which line goes to which teat, I wasn't fortunate enough to have one of those factory form factored pre-set rings that let ya plug em all in @ once. This one also doesn't have said "Teats" arranged in a circular pattern, these are all just splayed across the back of unit, no stamped numbers, letters, nothing
Haven't had a free minute to back trace these yet, got one now, and yep….raining blood out there currently
Par for the Course…
Thumbs up for sure, thank you for posting this. I was really hoping that you would show more of the vacuum lines control. My wheel is somehow broke.
can i pay u to restore mines , my ac switch wont blow on high
Just did the same job on my 85 t-type control unit but I had the big idea to disassemble the vacuum switch/valve to make sure it was clear and clean. Realized there’s no index on the valve and not sure if I’ll be able to reassemble it with the valve gasket oriented properly with the holes in the valve body (hope that makes sense). Did I screw myself, or is there a way to reassemble the valve properly?
I don’t have high speed and my cold lever won’t go all the way over to cold maybe 90% of the way
thanks I have a 92 s10 with the same switches
