2004 Pontiac Montana a/c fuse blows as soon as u put it in . Blows hot air only

Posted by on

1 Answer

If the fuse blows as soon as you turn the A/C on, the compressor clutch has failed (shorted). Simple repair.

If the fuse blows as soon as you put the fuse in without the A/C on, you have a physical short in your wiring.

I would suggest replacing the blower motor resistor. When this component fails the blower will only work on one spped or none. This is a very common issue with all automotive models

SOURCE: My air conditioning blows hot air. Won't accept

Is the system low on Freon? If not, you most likely have a bad A/C compressor, or a bad low pressure switch.

SOURCE: 2004 MALIBU MAXX A/C BLOWS HOT AIR

Could be several things. The fuse relay to the AC compressor could be bad. The system may need to be recharged due to lack of refrigerant the compressor will not work unless it has enough.

SOURCE: 2004 chevrolet suburban AC blows hot/cold at same time

You need to replace the drivers side temp actuator that is located on the left side of the HVAC box. It is retained by 3 screws and is fairly easy to replace.

2004 Pontiac Montana blows hot and cold thru vents even though the air conditioning is on. Mechanic says have to take whole dash out to get to the vent doors to fix it. Is there any other solutions?


The problem is within the airflow box, either a stuck or broken flap. It will need to be accessed via dash removal, (not as scary as you think).

It blows out hot air even when the air in the front is cold


Hard to read your question, do you mean it blows cold air out of the front vents and hot air out of the rear passenger vents?

If the air coming out of the front is just cool and not cold, and the rear vents are warm, you have low freon and need to have it serviced.

2002 Montana, A/C not cooling. blows hot air.


Sounds like a gas leak..
Most efficient way to handle that is - go to a ac specialist.. They will put more gas in with a die.. Then a week later they will check it again and a floresant light will spot the die - should there be any leaks.. And that way you will know exactly what you are dealing with..

Hope this helps !!
Rate me good ;o)

2005 Pontiac Montana SV6 heater blows cold when slowing to idle


How cold is it there and does your engine cool down any while going slow? If it does it may mean you need a hotter thermostat installed, My first thought would be to check the coolant level in the radiator and the coolant reservoir! Hope this helps and Merry Christmas

2004 Pontiac Montana blows cold air in defrost


There is a mix damper inside your duct that controls the heat over heater core and ac evaporator that to your floor and one to your defrost. it is probable an electric actuator, that is not functioning properly. If yu can locate it and manually move it, you might have to remove the actuator motor first, you should be able to figure out your problem, I hope this helps! merry Christmas!
