A/C on '98 Grand Caravan only blows HOT AIR!?

Question

Okay, I had my freon recharged, plus my serpentine and timing belts, and the tensioner replaced (which Meinke said would fix it), and the A/C still only blows HOT AIR, no matter what setting it's on. Please help!!

Answer 1

ok I need more info. Run the car. tell me if the compressor clutch is turning. If it is, is the low pressure lines cold and sweating ( the low pressure lines are the larger lines). If they are sweating, you have a ventilation problem in the HVAC box. If not, you need to verify that there is refrigerant( both gas and liquid) in the system. if the compressor still isnt turning after verifying, the refrigerant it is an electricalproblem; or the compressor is locked up. you should check that as a first step in diagnosis anyway. Now the grand finale is that if the compressor is turning, the compressor clutch is spinning, there is the correct amount of refrigerant in the system with no audible or visible leaks, but still no cold air from the vents, check for a blockage, usually contributed to a defective thermal expansion vavle if equipped or a plugged orifice tube. But yes, also the evaporators under the dash are good for leaking. Good luck

Answer 2

First,u have to check if the freon hasn't leaked out,common problem with caravans,as they have behind the dash board en aluminum type radiator,which i don't know what it's called,that is part of a/c that goes bad when that vehicle go over 100k miles,if the system still has freon,u need to know if the a/c compressor clicks on when u turn on a/c unit,u should hear a click after u turn on the vehicle and turn the a/c unit on!Note:meinke should have check the system for leaks before recharging,cuz freon is absent when there is a leak involved!

Answer 3

well it might have already leaked out or they didnt fix it right ??? take it back.........
