You first need to have your gages hooked up, motor running,AC on, Next read the gages paying attention to the low side,It should be around 34 to 40 PSI aprox. with the engine idle around 1000 RPM. the high side will vary due to ambient temp. (if its about 100 degrees out your high side could be 275 to 350 PSI). If those readings are OK and stable NOTE: I would keep an eye on the low side pressure to see if goes into a vacuum after a period of time, this would indicate a blockage-probably water in the system,where the water is you would see frost on the outside of the a/c line. If none of these things show themselfs I would next look at the air distribution system, 1-is their a hot water valve for the heater core that is not working properly? or no valve in the system,then there could be a air control door not working (I would look for a vacuum line from the motor to the air distribution system unpluged,split or cracked.(listen for a hissing if you can). If thats all ok i would look to actualy see if the air door to control air blowing through the evaperator
my Chevy cobalt 2005 keeps blowing the fuse everytime i put my windows up or down i had the door wireing replace a new window motor replaced new switch and it still blows the fuse what can the problem be
Plug wires are installed incorrectly.
replace or repair. It will only get worse.
check the fuse and the ground connection
Change the hall effect sensor . it is located under the distributor cap
No, I believe they stopped in 2007. Probably a result of not changing the look from 2000-2007, other then some small interior changes.
Heater Airbound? Heater control cable not working? Heater core plugged?
check all brake bulbs a filiment may have shorted out
why does the fan still run on the unit after it cycles is over. but it is blowing hot air not cold
It will affect the speedometer but the tachometer will still be accurate.
my 99 did this. Theft deterent module/ relay had internal short. Then they also found a short in a wire.
A possible problem could be you power wire is pinched somewhere causing it to touch a ground which will blow the fuse.
