Need help with A/C

[pym19109]

Hello,

Last night I went to take data logging with my new tune, I drove my car to the gas station and check tires pressure and after that I took OFT and plug it, I start the car and found that I didn't plug OFT to the OBD port tight enough and OFT keep power on and off many times. Then I stop the engine and plug it again and found that A/C does not blow cold air as it should like before as I drove to the gas station. It keep blow hot air until turn A/C to almost LO mode it will blow cold air. What do you guys think where is the problem ?

Cheers

I'd suggest you check the AC fuses (one under the hood and two under the dash).

If that's not the problem, I suggest you disconnect the negative battery terminal for a minute, then hook it back up. Maybe you have confused the AC system.

If that don't do it, I suggest you wait till morning - sometimes things in your head will fix themselves over night -

If it still don't work, take it into a dealer or shop and ask them to check the AC system.

Where in the hell is "TH" - ??

Flash back to stock and pull the battery for a bit. Also make sure the A/C clutch is engaging when you turn the a/c, if not check fuses and relays. I am suspicious that you may have a lower refrigerant charge and symptoms only started appearing recently.
