    you may have to re charge your system. you can go to your auto store and get a can of refrigerant with a gauge on it and once you hook it up the gauge will at least tell you if your system is fully charged or not

First off is the clutch on the ac compressor engaging when you turn on the unit...If it is not make sure it is getting juice by using a test light or meter...Assuming it is all fine to that point locate the low freon switch and unplug the connector off of it and take a piece of wire and jump it across the contacts inside the connector plug, if this causes the compressor to engage then it is either low or out of freon. Now you need to determine if it has a leak or you can do what the rest of the world does and just add freon and hope that it last for a while.They do make a sealant for it also. More than likely the evaporator has a leak but hopefully not...just remember to jump out the low freon connector or it won't **** in the new freon...

Unable to get my 2003 chevy blazer to start. has been acting funny. the hot air has been running cold and takes the ac a long time to get cool. the engine runs hot.


get a mechanic to have a look ,water level low hence the heater is cold and ac taking a long time to cool because the fan isnt starting up when ac is turned on ,Sounds like your fan is playing up and you may have cooked the head gasket??
