A/C issues.. Are these normal? - Page 6 - ZR-1 Net Registry Forums

Just spotted this thread and am having similar problems. The idea of the suburban blower sounded interesting. I checked both on Kragen autoparts. These are the blowers on the '90 ZR-1 and the '95 suburban. I'm not sure which one would move more air.

Has anyone installed this blower motor and did it help?

Now that we've had our first 100' days here in SoCal I'm interested in this again.

I just checked my blower motor and noted that it's getting 11.4 volts on fan speed 10 with the A/C on at idle. Seems about right in terms of voltage. Anyone else checked their's for comparison? Any idea what amperage it should be pulling?

It's still an issue of air volume for me, it gets plenty cold.

I bought the blower motor last year and never changed it out. It looked like it would be a hassle to swap it out. I don't drive my Z daily anymore so I just put it on the backburner.

One thing I should mention is that I wrapped my headers with heat blankets and wrapped the ecm with a thermal blanket and my car runs a lot cooler, the AC works better, and the heat related electrical gremlins are gone.

Its a simple job just relax the inner wheelwell bolts in order to get the motor and the squirrel cage out. Its a 45 mins job top. Make sure you make note of the condensation orafice tube location. Very simple.
