Im new to here and new to ford ownership. Car is a 91 Escort GT. Ive had it for 2 months now. Heres my problem. My 91 ford escort gt has no blower no windshield wipers or no sunroof. Checked all the fuses and there all good. When the car is on and I have it running I turn on the wipers and the RPMS go from just under 1000 RPMs to just above 1000 and if I turn them off the RPMs drop to around 500 RPMs. Same thing with the heater/AC. My brothers a mechanic and has no Idea what it is. If anyone can help me out I would be completely indebted to you.

 

Would you know how to adjust idel on my ford escourt gt. It idels at 2,000 takes a half hour or more to drop or is there a way to disable it dont rilly nead it
