I enjoy a challenge, but this looks to be borderline sadism!
There are @ 12 separate components that can render this system inoperable from one failure - to nothing at all.
My ATC in my recently acquired coupe, is completely dead - no blower fan, and no reaction to any push button selection.
I have desided to start by replacing the 50 year old underhood vacuum lines to the "control circuit" and "slave circuit" systems. The next step was to see if the 2 systems vacuum resevoirs were functional. Control side
Slave side - no vacuum will hold. I decided to bypass the slave can and see what happens inside the car... Well I now at least have a distinctive vaccum hiss at the selector switch! And as I select modes I can hear activity in the mystical black control box in the kick panel
I have a nos switch on its way to me - and will swap that out, as I suspect it is one of my culprits. Ive looked into replacing my slave Rez - but I wanted to diagnose, and possibly repair mine - as it appears to be in great condition, but needed to make positive that it was not leaking from the seams- Using a bucket of water, and the blow gun on my air hose I submerged the can up to the trico check valve and gave a shot of air into the can -alas I found the only leak to be around the small grommet seal of the check valve into the can, and it was significant!! I dried it off, thoroughly cleaned up around the seal, and applied a nice bead of "right stuff" sealant, I will recheck tomorrow evening to see if it will solve the leak. I purchased 4 generic vaccum check valves and line adapters, and I plan to replace all 4 that are currently in the vacuum line harness. I will add more to this thread as I continue! Any other tips or advice would be much appreciated!
