Could be a number of possibilities. However, the most likely is loss of freon. The O-ring seals at a number of line connections tend to leak over time. There are other mechanical and electrical possibilities but you should first have someone check the freon charge with a set of gauges to measure the pressures. It might cost you a bit to have it tested but the pressure reading will tell you a LOT of things. In the long run it will save you money over guess-work.

For a long time, when I've turned on the air conditioning, the check engine light pops on. If I drive far on a hot day, the car dies and won't start until it cools down. In the last couple of days,

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?

The air conditioning system will only blow cold air. Regardless of the mode, I can only get cold air. Can you give me an idea on how to fix the problem? Thanks Don 615-653-3834 drcamp117@comcast.net


The air conditioning is supposed to blow only cold air. Are you trying to get the heater to blow hot air? Make sure the temperature selector is in the hot position.

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
