1996 Buick Park Ave. V6. 3800. Heat only blow out the driver side. Heat may come on sometimes on the passengers side after turning up the temp. with the passenger climate controls and then turning off the car and restarting it. Then goes back to cold withing minutes. Is the damper controlling the passenger climate malfunctioning. If so how do I access it? The bearings in my AC compressor are going, if that effects it at all.

This will prove fatal in sufficient quantity. Therefore, drain coolant into a sealable container. Coolant should be reused Unless it is contaminated or several years old.

Protective gloves should be worn when dealing with engine oil. Wash exposed skin immediately after contact with oil with soap and water, or waterless hand cleaner.

SOURCE: 1991 Buick Park Ave. climate control stopped

Check to make sure that you have enought freon to engage the compressor, then you will need a flow chart to take you through the rest of the steps necessary to diagnos this problem. The Electrical system manual for Buick is the only one that will have the proper information for you to walk through the steps to dead head it. There is a HVAC programer that is behind the floor heater duck work. It has a numbering system that goes from (2) rows of pins that go 1-16 for terminals.On terminal 5-7 with ignition in run position, you need bat. votage. Terminal 10 & 11 you need 4-5 volts. Neither 10 or 11 should be unplugged just yet since 10 feeds 11 pin. If there isn't any voltage at these pins, check for corrosion on the pins theirself, or for the pin that it may have slipped back out of the connector. Good luck.

92 buick park ave only blows heat through defrost


Sounds like you might have blown the BM unit. As far as the vent selection goes, I worked on a Buick LeSabre a few years ago with the same kind of trouble. There is a vacuum distribution block down under the glove compartment that directs the route air goes. It is notoriously trouble. In my case the block was poorly formed. Sometimes the vacuum connections on the block are plugged, sometimes they crack or break off. Unless you are a full blown Mr Fixit you just need to replace the block.

Driver's side heat doesn't work


There is a problem with the drivers side air mix valve. I have seen several problems with these. Sometimes the air mix valve (door) gets stuck and when you try to change it the air mix valve link can pop loose, or sometimes it breaks. Sometimes it also breaks the bellcrank on the door itself. The programmer unit can also be defective. Please refer to the picture below. The thing to do is to remove the lower hush panel and possibly the glove box assembly so you can get a good look at what is going on. Then switch the driver's temperature control from hot to cold and back again to observe the movement of the programmer actuator, the mix valve link, etc. to determine where the malfunction is.

I have a 1998 buick park ave ultra and the driver side air blows heat and the pass side blows cold


assuming you have an electronic controlled (digital) dual zone system, it is most likely your heater blend door motor has failed, check and see which side is operating and buy the one you need and replace, it has 2 or 3 screws on the side, i think size is 4.5 mm or 5.5 mm and you have to take off lower plastic cover under dash and remove screws which go on horizontally... install heater door with temp swithched to the middle, move door to middle, if not you need to place new motor into plug before installing and turn temp to cold, then turn by hand the white blend door tube to match motor then install... make sure you turn off ignition when working,,,
