Hello I have a 1993 ford aerostar 3.0L. When my engine is running it idles fine. As soon as I turn my heater on to floor, vent, or defrost within a second or two my idle jumps from curb idle to high idle. This happens continuously as long as my heater is on. If I turn the heater off the idle is fine. (Ex. Up, down, up, down, updown etc.) I think it might be a electrical issue. Any suggestions would be great. Thanks
have the same problem?
