Buick Park Avenue, Sedan

The unit is electronic from what I find on that car. There is an actuator motor that controls the door movements and the blend or temperature on the driver and another on the passenger. That has gone out of some Pontiacs that probably have a similar unit to that one used in the last design of the Park AVenue. Finding if the door is being moved requires some upside down time under the dash and button pressing.
The AC giving cold for a time suggests that it has a leak. One common symptom of the 2000+ H Bodies is that low freon leaves the driver side warm and the passengers get air from the cold part of the evaporator.
The unit needs to be put on gauges and a check done.

I had a similar problem with my 99 PA, but it was with the heater. The vent door became stuck on the passanger side. So the driver felt the heat but the passanger only felt the cold air from the vent.
I took it to the dealer who said it was a stuck vent door. The would replace the solinoid (or whatever controled the door) for $250. They already charged me $75 for the diagnostic (and used it to close the vent door).
I chose to leave it alone. It does come and go very intermittently. And because I usually drive alone it's not a problem for me.

Sounds like the system has a bad leak. If you got cold air for a few minutes, the system was working properly, until the refrigerant leaked back out. You could take it to an A/C shop to see where the refrigerant is leaking (some parts are cheap to replace, some aren't) but it doesn't look like you'll be able to throw a can of R-134 in it and be good for the summer.
BTW, if a '97-'05 Park Ave system is low on refrigerant (but not completely out), the system will often cool only on the passenger side. It has something to do with where the inlet and outlet tubes of the A/C core are located relative to the airstream. I spent quite a while trying to diagnose a faulty air blend door last year, only to find out that my air blend door actuator was perfectly fine and the system was just a little low on refrigerant. Adding more refrigerant restored the system to bilateral functioning. (Note--do NOT do this until you've ruled out a blend door fault, or else you could end up overcharging the system and wrecking the compressor.)
What you may want to do, if you really like the car, is get an estimate from a *quality* A/C shop on how much the system would cost to fix, and then ask the buyer to knock that much off the price. Don't take it to an el cheapo shop, though, as the Park Ave system is more complex than your typical A/C setup.

I don't know about questions 1 & 2 but number 3 I know about. I have a 1997 Park and had the same problem with the driver's door. The inside of the door has to be taken apart to reach the problem. As repairs go these days, the entire latch showing outside has to be replaced and has to be painted to match your vehicle. Parts & labor $140. My Buick dealer did the work.

Thank you for the great advice about my a/c and other questions. The PA is in the shop today. It turns out the condenser was leaking and they are fixing everything for 560.00. The owner is knocking that off the price so tomorrow I will be the proud owner of a 99 PA Ultra.

>condenser was leaking
Thanks for coming back to tell us what you found! Good luck with your new PA.

This was common on my last PA as well as the one I own now. I read in the service manual that when the rotors are put on, the have to be checked for lateral runout. They have an extensive installation technique that includes cleaning both mating surfaces and then checking the lateral runout with a dial indicator. The tolerance is .002".....two thousandths of an inch. Smaller than a human hair (or at least mine) which seems to be extremely tight. For such an easy thing to get on and off, I will bet you a million $$$ that NO mechanic at the shop has ever done that. But, if that is what it requires, you could in your own driveway, spend some time and do this. I replaced so many rotors on my last PA that I will probably look into this. I have the tools at home, so it wouldn't be a big deal other than the time.
#448 of 519 PA ABS/Trac Off lights
Jul 24, 2008 (9:28 am)
I recently had the dealer get the codes from my PA. It had it's TracOff and ABS lights on. They told me that it was the FL hub, which I then replaced at home. Now the lights still come on, but only after the car is put into Drive/Reverse. I thought at first it was when the car moved, but managed to coast all the way out my driveway without them coming on and then they only came on after I put it into drive. I know the old hub was bad, I checked for the resistance and found none (plus it was leaking) and this new hub doesn't immediately trip the light which the old one would do. Any ideas????

Jul 25, 2008 (5:27 am)
Today a garage has looked at it and looked for codes. They saw the LF hub in the history, but no codes are stored now and none are pending. Yet the lights for ABS and TracOff are still lighted. Sometimes from the start, sometimes if I roll but every time I put it into gear. I'm thinking a short somewhere maybe? Is there a fuse anyone knows about that I can pull to reset the BCM? I think that is the module for chassis? Anyone?
#450 of 519 98 PA left rear speed sensor cable (ABS)
Aug 01, 2008 (1:47 pm)
ABS light on. Chased problem to a resistance problem in the cable that runs from the speed sensors in the left rear hub to the main wiring harness. GM wants $250 for part. Anyone solved this problem other than new cable?
