I have a 93 Mercury tracer and recently my heater blower motor wont work (I have taken it out and hooked it to a battery and the motor spins). When the blower motor quits so does my windsheild wipers and electric windows wont work. When the windsheild wiper and windows work so does the blower motor. It is a intermitent problem, somtimes it works and somtimes no work. Thanks for any answers.

First of all, what size motor do you have? You wouldn't think it would make a difference in the wiring, but it does. Please advise.

The engine is the 1.8 liter.

After scouring over wiring diagrams, everything points to the accessory side of your ignition switch. To test this theory, when the on power condition exists, turn the ignition to off, then to accesory and see what happens or, just change the switch.

Thank you very much! I replaced the ignition switch and now everything works perfectly!
