well, the problem is i drove around for a while till it got ot the point were on highway there was cold (not too cold but some) and at a red light there was hot air blowing......um also if you hit max ac button the fan should be on if not its not working but if yo look at the sensor like i said this is what happen to me.

1. aux fan twitched never turned on replaced 300 on ebay
2. it was said that if you drove around with no fan the pressure could have been too high which could result in freon being release. so i had the air vents form left ot right go codl to hot. so i paid 80 bucks to drain vacuum and refill but worked for a bit then still started with the ac only working when driving aroudn and would finally would turn on automatically so a memeber here mention weird sensor on the line from compressor to radiator ....
3. after much research online i finally found out that it s the high pressure sensor monitor and it was 40 bucks prom partsgeek.com
4. still have not replaced the sensor cuz its winter and you have to drain the system then also change teh ac resevor tank or expansion tank and replace sensor then vacumm system and refill...

but ive only spend 300 (some change) so like 330+80+40+30(can of ac refill) === about 480 so i think its better this way than dealer or and indy do it. since im replacing most the parts its realy easy.

oh also make sure the compressor is working too.....so turn ac off then you can see belt turning but the clutch on the compressor is not moving and when ac is on you should see it move spin so need to check that to make sure its no the compressor.
