1988 Buick LeSabre Air Conditioning Problem

Very little air is emitted thereby not allowing the cool air to be effective. Have been told that the vents are not opening or do not stay open. Tried to open vents from behind the glove box with just a little improvement. I would be satisfied if the vents were frozen open year around.

There are two radiators in my 1991 Buick LeSabre. Which ones do which, and are they connected?


No...one is your engine radiator ( the big one) which cools engine.
The other is not a radiator..it is the air conditioner condenser that releases the heat generated from the air conditioning system cooling the interior of the car.

When i turn on my air conditioner on my 2002 Buick LeSabre my fuse blows for the right fan. Do i assume the fan is bad? The left fan still works when the car gets hot.


My air conditioner on my Buick has a full charge of Freon and when it is hot out I don't get the cooling power in the cabin as I have it on low switch so when I put the switch on the high the Air doesn't change to cool the interior on high. I had the Freon tested and it still doesn't work properly and I wonder if there is a sensor that doesn't allow the system to cool properly?

Sounds to me like you have a leak leak somewhere. They can put a dye in the lines to find out where the leak is, Then have that fixed and get it recharged again. Its an expensive procedure though. I hope this helped
