SOURCE: 2004 chevy subarban blows cold air on one side hot air on other side

i was a GM mechanic for many years, the problem you are having is one of your mode door actuators has gone bad, most of the time it is the actuator on the drivers side that causes the problems, i have seen this many times, sometimes you can take it to the dealer and they can hook the computer up to it and recalibrate it but most times it has to be replaced , it is located under the dash in the area above your gas pedal.

SOURCE: 2000 Chevy Silverado 4X4 - Heater isn't blowing hot air

No your thermostat is stuck open which will not hurt the engine. but needs to be replaced, the thermostat is what allows the engine get up to operating temp. before allowing water to flow through the radiator and when it is stuck open it doesnt allow the engine to reach operating temp. so the heater never gets hot. I hope that helps you out.

SOURCE: 1999 Chevy Cavalier A/C blows hot air

More likely the recharge blew a o-ring and you have a leak. When your Cavalier was blowing hot air and a recharge fixed it that means it was low on freon which lets o-rings dry out, go back to the shop and have them leak test it. They use a pressurized dye to find the problem. If it's blowing it's not the cooling fan relay, they may have meant compressor relay but I'd have a leak test done first it's not expensive and easier that chasing unknown possibilities.

I have a 2004 Trailblazer and my rear a/c starts out blowing cold air but gets warm shortly after but the front a/c keeps blowing cold air all the time???? what could cause that ????

Just a little low on freon can make it get too cold and it freezs if you in position to check the freon level you'll find with the system on high and the engine reved up the low pressure is below 25PSI. fill it to reved up is above 25 and your problem will go away. Low on freon will make it cold enough to frezze up and then warm up as the air does'nt go though the ice. it'll work good as you start up till it frezzes and after it's stopped up with ice it blows warm (it's really too cold). the more freon in the system the warmer it'll all blow because all the pressures are higher and it's the difference in pressures that make it cold.

Hi sorry but more than likely the passenger side control rods have sized or broken this could be quite a big job will need looking at a garage if you don't know what you are looking for sorry.

Hope this helps.
