My a/c control unit in my 75 is frozen on the right size,what causes this? Would I have to replace the whole unit? Please help if anyone knows.............thanks Ray
First check to make sure it is not hitting on the stuff under the console. A few times I had mine out and before I got everything back together all the way it would rest on the shifter bracket. Neither wheel would turn until I picked up the console a little
I didn't take the console apart but is there a cable that hooks up to the unit? Maybe to the heater control valve,because that is broken. The other side moves freely,a/c,vent/bi level.etc....
No cables for AC cars. There are electrical and vacuum connectors under there.
You can get a rebuild kit for HVAC controls.
Check your information again brother. FACT: There IS a cable that controls the hot/cold door...and that goes for ALL A/C Corvettes up to 1982...and even 1984 and later with manual controlled HVAC control heads also.
