AC and Blower

1997 with 150k miles, passenger front AC is ice-cold while driver's side front AC is obviously warmer; back AC is OK. Front defogger blower only works on driver's side, not passenger side, Replaced cabin filters,

thanks.

I would suspect you have a faulty blend door motor.

Thanks, roadrunner, is this a difficult thing to fix?

It can be.

I watched my independent tech replace mine in my '02 Tahoe and it entails pulling half the dash apart to get behind things to gain access to the blend door motor. My receipt says it is called a 'temp door motor'.

The motor cost $80 and the labor of 1 hour ($65) (includes calibration). So, if I had been able to do the work myself, I'd have saved the $65. ($ are CDN)

In other words, it's more time consuming than anything, but once you're there, a couple of screws and electrical connections later and a reversal of the procedure to put the new one in you're done.

Sounds easy, (and is once you know what you're doing) but I'm always afraid I'm going to damage the plastic parts/clips and so on.
