Re: A/C issues.. Are these normal?
My problem is the fan seems to blow the same on settings 6-10 as it does on 5. I think the blower motor isn't spinning any faster at the higher settings.

Blower module is between the control head and the Blower in a C68 car.. on my C60 it is a resistor network ( 4 speeds) for the C68 it is an electronic module..
there should be a Diagnostic chart for your issue in the FSM

Re: A/C issues.. Are these normal?
Update: I ran the diagnostic check and there were no codes stored. I checked the blower ouput on te different fan settings with the ignition on and engine off and the blower motor does increase output through each of the fan settings. The problem is the outpur is very weak, that's probably why I couldn't tell any difference while driving.

Re: A/C issues.. Are these normal?
Pantera, maybe your motor is bad..
if you swap let us know how it works out. I am debating on ordering a Suburban Squirrel Cage to see if it will fit in our air box. not convinced 100% that the motor will make a difference, but might. Also I found out the 94-95 ZR-1 and 94-96 narrow body cars used a different Condenser, must be the parallel flow condenser like I have to be installed..

Re: A/C issues.. Are these normal?
Did anyone figure out which Suburban parts work or not work? It is getting hot in IAH again.

I am thinking of trying a Suburban Squirrel cage on the Corvette fan though.

Re: A/C issues.. Are these normal?
 Some real good deals floating around on ebay for rebuilt clutches, and new ac compressors some without clutches. Maybe clutch slipping?Your Climate control head will show stored diagnostics. Some how to's on Zr1registry.net J. |
