Question about 2006 Chevrolet Colorado

1 Answer

In my truck, i don't seem to be getting any cold air with the air conditioning is on. I have ruled out the ac compressor because the clutch engages when the ac is turned on and the ac lines going into the firewall are cold. The only air coming out of the vents is hot air from the heater core. I am led to believe one of the directional doors or flaps that controls the mixture of cold and hot air is not working. Any ideas? Is there a common malfunction with these trucks with the temperature control switch? I was hoping to have a good idea of what to look for before i tear apart the dash.

Ac is not blowing out cold air. You have to put gages on the system and it shows its has freon.Checked all fuses and relays. The two fans in engingine compartment do not come on when the ac is turned on but does when the engine gets hot. The compressor engages when turned on also.
If the magnetic clutch engages the compressor and still no cold air could be still low in freon or the HVAC unit.

Blower motor not working all the time...if I bang the dash near the glove box, it comes on then works great. Is this the switch assembly, the resistor problem, or should I be replacing the blower motor?

Ac won't get cold anymore power to compressor but won't click on clutch won't engage possible problems are compressor or evaporator what do you think?


Has the Freon been checked with a gauge to see if there is enough Freon to allow the system to work. Low or no Freon will not allow the compressor to engage. The low pressure switch is most likely activated due to low freon, and will cause this condition.

I have a 03 honda civicand the air conditioner wont work? it doesnt need recharged and the light comes on when i push the button but i get no cold air? any ideas?


I have the same problem right now, and from what I can figure, it looks like an intermittent thermal protector switch on top of the AC compressor. My 2003 Civic air conditioning works fine for 20 minutes or so and then stops working. If this switch is faulty, the compressor clutch won't engage and you won`t get cold air. I will get it replaced soon, but it seems like the access is not easy.

Car overheating and ac is hot and have 0645 code


There is an electrically driven clutch on the front of the air conditioning compressor which engages when air conditioning is required The AC compressor has a fan belt driven wheel on the front of it. The belt turns this wheel all the time. When the a/c is off this wheel spins freely. When a/c is required the electrically driven clutch engages this spinning wheel to supply drive to the a/c compressor shaft. The 0645 code concerns a fault with this clutch.

My 2002 Expedition air conditioner will sometimes blow hot air and others cold air


I would check the following possibilities:
1. Is compressor clutch working? - You need to do this when the ac is blowing hot air only - locate compressor drive pulley on engine - rubber belt wraps around it. Start engine and set to max ac. When the ac is blowing hot air, look at the center of the compressor drive pulley using a good flash light - watch it for a while, it should be spinning with the pulley - this means the compressor is engaged. If not, the compressor is not engaged. If your ac is blowing hot air, then the compressor should be engaged and running (trying to cool). If it is not engaged, then your compressor clutch is probably going out. Could be low voltage to clutch, but more likely the clutch is worn out and only working some of the time. Note: if working normally, the compressor clutch will engage and disengage in cycles- but the air should always be cold. If clutch is bad, compressor would need to be replaced (sold as one unit). This is tricky to diagnose and could take some time - you need to do it when ac is blowing hot air but set to max cooling.

2. Low on refrigerant or refrigerant has moisture in it? If your ac blows cold initially after being off for a while, then heats up, and continues to regularly cycle back and forth between hot and cool air, then the system may be low on refrigerant or the refrigerant may have moisture in it that is freezing and restricting refrigerant flow. An a/c shop can check refrigerant level and even replace refrigerant if moisture is suspected.

Could be other issues, but I would start with these.

Good luck

Screeching noise, then a/c stops blowing cold air. Still blows air, just not cold air.


it could be the air conditioning clutch going out. to check turn your car on and idle it with ac on and hood open. at the ac compressor it will have a pulley on it with a clutch that engages when the air conditioning is on. if it engages and disengages it can be the clutch itself has gone bad, the ac clutch will also disengage if there is not enough freon in the ac system, will also engage and disengage if the pressure gets too high in the ac system. Depending on the year of the vehicle it will disengage at full throttle and come back on when you are not at full throttle.
If it is a metallic sounding screech for example take a coke can and drag it across pavement kind of sound it could be a bad compressor or a bad ac clutch. If it is a more rubbery sound for example a car spinning its tires kind of noise it could be a loose belt.

1. Check to make sure all belts are tight under hood
2. start car and look at ac compressor to make sure compressor pulley is turning and that the fan clutch is engaged spinning

Air conditioning


when it gets warm , open the hood and watch the ac compressor , is the clutch still engaged and the front of ac compressor spinning , is the large tube out the back very cold , the other tube should be hot or warm.
if the air is warm but the ac is working correctly under hood then you have a issue with the vacuum controls on the inside of car.
