ac warm air

hi new here so thanks for letting me in. my 2009 tacoma blows cool to cold air out of the drivers side upper vent. all the rest of the vents are not cool or cold. checked actuators and looks like there are 3 of them , they all seem to be functioning correctly. i am thinking recharge? or am i missing something else? any idears would be great. thanks

 

Sounds like it's low on refrigerant, check and see if the suction line (see picture below) is cold (truck running, A/C on high), if it isn't or is barely cool your either low on refrigerant or there's another problem in the refrigeration system, at this point you will need someone with gauges to hook up to it and diagnose further.




If you DIY don't use one of those suicide cans, charge it properly with gauges and don't use refrigerant with stop leak in it.

 

thanks, i didn't no that i will check to see if it is cold and go from there ...thank you for the quick response.

 

May or may not be related but here’s the issue I had with my AC. if anything else it’s a good read.

Sounds like low charge. One thing you can try is changing it to recirc mode (on) and see if the air coming out of the vents gets any cooler: especially the coldest vent. If any of the other ones get cooler, low charge is the likely reason.

Welcome to the forum.
