The AC on my 2000 Galant blows cold but the air flow is weak

Could be blend doors not operating correctly
ButI'd guess the blower motor or resistor is go in outd

Can you hear the blend door moving when you change the temp from cold to hot or vice versa? If not, then you need new blend door actuator. Also check the heater core for any blockage. (2 ways to tell....run the car til normal temp, and turn on the heat and feel the hoses by the firewall...if one is hotter than other, there is a blockage inside the heater core. Or disconnect both hoses at firewall, and put garden hose in one of those 2 open tubes and turn on the water...good flow or weak flow coming out of heater core tube? Weak flow means blockage) If there is a blockage, time to get new one.

The pressure sw. on the dryer maybe weak but the way you explain it I think the sys is low on Freon. The reason for this is you said it did not get that cold. I would add a half can or one to the sys and see if the compressor cycles longer. Hope this helps.

What was the "flaw" in the friends AC system that took two years to figure out? Maybe yours has the same "flaw" and it's taking 4 years to figure out?
Don't expect your AC to blow ice when the ambient temp. is 100 degrees and you are stuck in traffic. It's not going to happen...
If your compressor is weak and not compressing properly, efficency goes down. How many miles on your truck? They wear out, like any other moving part. I suggest you have a complete evacuation done with a deep vacuum, this will remove any air or moisture. Recharge to mfrs. capacity. Clean the outside of the condenser and radiator of all dirt, debris & bugs so air flows freely....Pressure sensors and temp. switches can be tested, if they are bad, replace them.
I hope this helps.

sounds like u guessed right blender door is getting stuck motor is weak or mount is cracked

your air con needs re gasing

try driving around for almost 4 months and the damn thing wont blow cold. try spending thousands of dollars and it still being broken. and trying driving in florida in upwards 115 degrees with no cold ac everyday. you only have to wait 30 minutes? count yourself lucky!

This is a blend door problem, this door diverts air either throgh the heater core or the AC accumulator core, it either provides hot, cold or a mixture or blend, this door is deep in the dash and in most cases the dash must be removed to service the little electric motor that operated the door.

Please check for any blockage and in the ac duct, IF the duct is clean you need to refill the AC gas and get it serviced as the AC thens to weak over the years ........................







good luck................
