I having problems with my ac& heater. I checked the fuses and relay under the hood and still fine. When i drive on the freeway i can feel the cold air and if i change it to the heater i can feel the heater but only while going at fast speed. Does anybody know what the problem can be? Any help is appreciated

 

There has been problems with the blower motor's wiring harness and the resistor pack which control the blower's fan speed. Does the blower fan run at all ? Check some of the recent posts on this for testing procedures.

 

When i hit the switch you can hear the fan starting up but won't start up till moving at least 45 mph not much air tho but vents do throw hot and cold. You know where the harness is located on the car? I'm from Cali so this heat is killing me with no ac and leather seats. Thanks.

 

The blower motor and wiring harness are located up underneath the glove box on the passenger's side. There has been some recent posts that could be beneficial in troubleshooting the problems with the blower speed.

 

Thanks i got it fixed the harness was burned out i replaced it now working good
