2008 MDX A/C issues

[oizhztl]

Hi all,

I was in the market and met a 2008 MDX tech seller.

I found the A/C doesn't blow cold air, rather blows warm air. I could hear the compressor engaging fine when it's on, so assumed the AC gas was gone.

It has almost 120Kmi, but still only 5 year old. Could this be a bigger problem? Any experience or suggestions?

If AC compressor clutch is engaging gas is there. There is a pressure switch and without gas, AC comp clutch doesn't engage. So that is not your issue if there is one to begin with...

I had an issue with rock flying through my bumper opening and punching the hole in the condenser, gas leaked out and AC quit. In my case AC comp clutch was not engaging for obvious reasons...

There is a minimum pressure that has to exist in the system before the compressor will kick in, but that doesnt mean there is enough refrigerant in the system. R134a pressures have to be pretty close to spec to work efficiently. If freon is low by 10%, it wont be very cold.

You can ask the seller to try re-charging the sytem yourself. The recharge cans can be found fairly cheap at auto parts stores or walmart.

Here's an example: Buy Interdynamics EZ Chill R-134a Refrigerant Plus Oil with Leak Sealer (18 oz.) MAC-134 at Advance Auto Parts

Add only R134a w/o leak sealant. If problem is something else, you don't want sealant potentially causing problems.

It could also be a faulty mix motor or controls issue. Try going to manual operation and see if cold air results. If suction return hose at firewall is cold (30-40F), then AC is working but air is being heated somehow.

good luck
