The fan works when hooked direct to power but no fan control in car. Turn fan to high and it doesn't work. Some one said it may be the heater fuse or a relay. Don't know where either one is located and how to check if it is bad. Any help would be appreciated
I aasume you mean blower motor for heater/a/c system.
Does it work on hgih speed only? If yes, replace resister.
Is this manual a/c or electronic?
Here is circuit for manual. check these three fuses first. 1, 17 & 10 in fues panel behind dash or kick panel by driver's knee.
If you have electronic, you may have a bad "blower motor speed controller". Get used at car-part.com. page with asterisk is lowest price. New at tascafordparts.com
it is electronic.

Thank you for your quick response. This is my son's car. We checked all those fuses and they look fine. We are not sure if his car ac/heat is electronic or manuel. He said the temp. control on his dash is electronic-lcd screen but the fan control is like a scroll knob. Does it sound like electronic or manuel? If it is electronic, you said it could be the blower motor speed controller, where is it located?
