Question about 1998 Buick Park Avenue
The heat is on the fritz in our 1998 Buick Park Avenue. If you turn the car on and let it warm up in the driveway, it works. As soon as you start driving the heat goes off. The fan continues but it blows cold air.
The heated seats still work fine.
From our research, it may be a broken thermostat and we would like to replace it ourselves, but don't know how to do this. The part appears inexpensive.
This doesnt sound like a thermostat problem, rather a restricted heater core.
The thermostat housing, however, is a cheap cross-your-fingers-fix, and can be located by tracing the upper radiator hose back to the engine. The housing the hose is clamped to is where the thermostat is located. Remove 2 bolts, and replace thermostat.

If you follow the top radiator hose to the engine you will see where it connects to the engine...you will want to drain some of the coolant from the radiattor but once you loosen the clamp holding the hose on you will need to pull the hose off and push it to the side out of the way. there are two bolts that hold the housing on that you need to remove where the hose was hooked up. once you take those bolts out you should be able to pull the housing out and the thermostat is right there.
i do wish to offer you an opinion on the thermostat i dont think its the problem..i think maybe your heater core is partially clogged and not letting the coolant get into the interior of the car as you are driving.if its blowing warm when you start it up and let it run and it gets warm and then get cooler as you drive thats going to be in the heater core since the thermostat is opening to let the heat in when you first start the car up to warm it up.
