El Camino 78-87 HVAC control unit repair

[@Helladamnleet]

AC Delco 15-71423, Gm 16042667, GM 1228343 if anyone cares what the part number on these are. They cost a lot. Couldn't find anyone making them BUT this seems like something that could be 3D printed

I was wondering putting a piece of regulator paper between the rubber and backing plate cut of the leaking between the 2?

[@Terrydepew5]

Did the cleaning fix the problem?

[@VideoServicesVB]

Yes. Sure did. 👍

[@84SS931]

Did you just use soap and water? Or lubricant also.

[@VideoServicesVB]

To be honest friend, this was years ago. But my hunch is that I just cleaned it. Maybe even windex, 409, purple power. Sry I can't remember. I dont have the car anymore.

@@VideoServicesVB I cleaned mine this morning after I watched your video and it’s working! I now have heat and ac blowing through all my vents. Thank you!
