    1977 C & K Model Wiring Diagram

    I ordered this diagram for my truck but it does not include the air conditioning option, which I needed. It is a very good quality 11" X 17" laminated schematic. I just got the correct diagram today so I have no further use for this one. I'm happy to pass it along to one of my square body...

    Nothing else is affected. When I key off, blower will still run. If I move selector to OFF, it all turns off and will not restart until key is on again. I suspect the blower relay is sticking.

    I posted this over in the "Parts Wanted" section as well but I'd thought I'd post here too, just in case. Looking for a reasonably priced stock AM/FM radio to fit my truck. Must have the connectors (plugs) on the rear. Do not want 8 track player or cassette style, just radio. Don't care what...

    AM/FM Radio

    Looking for a reasonably priced stock AM/FM radio to fit my truck. Must have the connectors (plugs) on the rear. Do not want 8 track player or cassette style, just radio. Don't care what year or if it's black or chrome, as long as it works and fits the hole. Cheers, Greg :cheers:

    One more question. Do you have power at this yellow wire for the resistor on the heater box with key off?

    Can I Get a Quick Check Please?

    Woke up to a dead battery this morning. Got a draw somewhere. Found that my HEATER/A/C fuse and my ACCESSORY fuse were both hot with key off. I don't think this is the way it should be. Can anyone here check their truck for me and see if they have juice at either one of these fuses with key...

    OK, I'm Completely Stumped Now!!!

    I can hear it leaking, pretty badly, at all positions.

    dvdswan, I have a Snap-On vac tester similar to that one which I used on the bench to test the switch when all the ports were capped. This showed the switch was leaking pretty badly. The test pics I showed were with constant vac that made my testing much quicker than having to hand pump each...

    Yes, as noted above, #4 port has direct vacuum on the factory connector. As I jumper this vacuum around to the proper hoses on that connector, all vacuum operated doors function properly. But with the switch in place, instead of the jumper hose, no functions work.

    OK, I'm Completely Stumped Now!!!

    OK, this is bizarre but it looks like I'm back to the switch. I hooked constant vacuum to port #4 with all other ports capped off and it would not hold vacuum, which I thought was a little strange. Then I removed the caps and ran the switch through all it's paces, moving a vacuum gauge to each...

    OK, I'm Completely Stumped Now!!!

    I've got about 16 inches of vacuum at idle, at the vac reservoir line coming in. I've got the same at the vacuum connector inside. I'd like to see it a a couple inches higher, but this should do the job.
