    1977 A/C Wiring Question

    According to the wiring diagram I found on this forum. I believe my orange wire is from the Recuc Over Ride Switch and goes nowhere. All of my wiring looks intact and I can't find the male connecting end. So I will just leave it loose for now. Thanks

    1977 A/C Wiring Question

    CSFJ the illumination light is there and connected up I just removed so the assembly could pull out farther. 75gmck25 I think you are correct I checked the voltage and when I slide the selector to Max A/C I get 12 volts from the wire. I still can't find the male terminal anywhere for it to...

    1977 A/C Wiring Question

    I have a orange wire coming from my vacuum selector switch behind my heating and a/c controls. On my 1977 Crew Cab. The wire it's self is about 6 inches long and has a black plastic female connector on the end. Does anyone know where the wire needs to go? Thanks

    454 surges when driving

    My truck is back to running like crap again. This time the truck runs really good when the engine is cold but as it warms up it misfires and dies. If I keep the gas pedal to the floor, it stays running but lacks power. When I let off the pedal it will die.

    454 surges when driving

    I believe I have finally found the problem. I just swapped the dizzy from my 1979 daily driver truck that runs very good. Into the 1977 truck and poof the 77 finally ran good very good. I found out today that a 454 has tons of power. I kind of did not want to put the dizzy back into the 79 but I...

    454 surges when driving

    Thanks I did check the fuel pump. I disconnected the fuel line at the carb and cranked the engine. I got many squirts of fuel. If someone knows the gpm of a stock fuel pump I may be able to check the rate of flow at idle until my carb empty's of fuel. Today I just fired up the truck and it...

    454 surges when driving

    My 1977 454 C 30 runs great and sounds great sitting in the driveway. As soon as I start driving down the road the engine bogs down and surges the more I press the accelerator pedal. Then once I shift into park sitting at home the truck run great again. This has been going on all this year. I...

    1977 Crew Cab Power Window Switch

    I finally braved the cold and checked the window operation. All the other 3 doors work correctly up is up and down is down. So I feel it's just a wiring mistake at the driverside window switch. Also I removed one of the rear door panels to see if a PO hacked in power rear windows. I believe...

    1977 Crew Cab Power Window Switch

    I have a question about my power window switch on my 1977 crew cab. I have not yet removed any of the door panels because of a fear of finding a huge wiring mess. Currently my 4 window switch is loose, my guess a clip somewhere is broken. All 4 windows go up and down like they should but my...

    Brake Pedal Does Not Fully Return

    Is there a possible way to unstuck the spool valve? Yes someone could have change something with the incorrect part. The whole master cylinder, booster, and brake line assembly all look like they aged together. Everything all kind of has the same surface rust over all the parts.

    Brake Pedal Does Not Fully Return

    I just purchased a 1977 C30 Quad Cab dually with the factory 454 and hydro-boost brake system. Currently the brake pedal does not fully return. The PO solved the problem by installing a pedal return spring. Is there an adjustment on the push rod somewhere so I can remove the 1-1/2" of play in...

    Are 1981 and 1977 Insterment Cluster Wiring the Same as My 1979

    Yep it was disconnect ground wire. Everything was back feeding through the headlight switch. I honestly think the the ground wire has been disconnected for a very long time. Now when I turn the ignition on a fasten seat belt light comes on. Plus I now have this neat light under the dash board...

    Are 1981 and 1977 Insterment Cluster Wiring the Same as My 1979

    After sleeping on the issue I feel that I might have a ground issue due to fact that my interior turn signal lights flash opposite the outside lights when the headlights are on. I also agree with chengny that everything is back feeding through the headlight switch. Now the issue is finding the...
