Ac blows cold when driving, but when I stop at red light it will start blowing hot air.
SOURCE: Air Condition Hot Air
there is a updated ac relay for that, go to your toyota dealer and buy a new mgt relay its located in the fuse box in the engine bay on the drivers side.
SOURCE: my 97 tercel ac is not working right. it blows
sounds like head pressures to high possible expansion valve plugged or bad
SOURCE: 2004 toyota celica will not blow hot air for twenty minutes
If the engine temprature does not reach the normal level as it used to, it may be the coolant thermostat.
Iif it does, it could be air diverter gates not working properly, cold air blowing at a a light could point to that. The diverter gates are located under the dash.
It also coul be the valuve that controls the water to the heater core, but unlikely cause of the cold air at a light.
SOURCE: The ac light on my Toyota Sequoia just started
replace the A/C magnetic clutch relay, its in the under the hood fuse box
