    I just started reading the forums and postings on these sites trying to figure out where to start to see if I could fix it myself rather than taking it to the dealership. Someone suggested a new cabin air filter. Is it difficult to get under the dash or behind it?

Is there a vent shutoff ? You will probably have to search under the dash for a leak in the duct work.......???

Drivers side vents are blowing warm air when in the A/C mode. Passengers side vents blow cold air.


There are actuators that open the vents...im betting that side's are stuck.

I have a 2003 toyota corolla. My AC would blow cold air for a min or two then when the compressor shut off it would no longer blow cold air or come back on. A new compressor was put in it but it did not...


the ac clutch relay is the problem. It is located in the under hood fuse box. It is a $10 part. The relay will make a clicking sound when activated but the contacts inside are burnt causing no electrical flow to the ac compressor. Simply unplug and replace. The relay is labeled M/G CLT .

replace or blow out the cabin air filter as well. It is located behind the glove box. Instructions are in your owners manual.

A/C on driver side of my toyota does not cool passenger side does.


well if the passenger side is getting air and its cold then you know the A/C is working..look under the dash and see if the plastic piping came apart to where it goes to your side of the vents...sometimes they slip off....and you can be blowing the cold air inside your dash somewhere....i doubt this but its not uncommon..but you can also have a blockage in your driver side vents...
