    When you say it quits, do you mean it stops blowing, or the air is still blowing but no longer cold?

Have you a/c compressor relay checked. also check your evaporator coor and your condenser to see if they are clogged to where the air will not flow threw. that can cause some problems for the a/c. if it cant breath it cant cool. all so i no this sound stupid but check your air filter to your intake. i have seen a dodge that would not blow cold air or much air at all cause the breather filter was completly stopped up

Only reason the A/C cuts out would be low on Freon. Being that way, the compressor on the engine(belt driven) will shut off and back on when has gone thru a cycle. Have the system drained and vacuum cleaned for a couple of hours. Then refill to proper level and should be fine.

When I turn my vent selector to defrost on the far right (air con off)the air conditioning comes on. The dash vents will blow ambient air, but defrost setting blows air con. Any ideas?

It's normal for the A/C compressor to come on with the defroster to dehumidify the air so the windsheild won't fog up under humid conditions. You can still control the air temp. out the vents with the temp. select switch.

BMW 318i 1999 model, air con not working


I had this problem before. There could be several reason.

1-Your air conditionner filter could be soo old and dirty, that you don"t get that good air condition.

2-Your air cond compressor could be giving low pression and so, no cool air.

3- You could be having a leak somewhere and so you're loosing gaz after it's filled.

4- Check also the fuse box. Seee if the AC fuse is not burnt.

thanx and don't hesitate to come back to me

I am experiencing the same problem with my 98' GMC Jimmy. I have a small leak in the A/C compressor, so I have to refill it with freon at the beginning of every summer. Also when shifting out of 4HI to 2HI it has a hard time, and in fact make a whining sound when I'm de-accelerating. I think the cause of this is my transfer case motor, but I'm not sure. Can anyone confirm this?
