Blower motor wiper and stereo stopped working on a 1990 Plymouth Acclaim. I checked all the fuses but they seem to be fine. Are these things cotroll by a relay?
They are things that are all controlled by the "accessory" circuit of the keyswitch, but don't just run off and replace the keyswitch. Check the wiring, see if there is power to the accessory terminal block when you turn on the keyswitch. You may need to find a book that contains a wiring diagram to be able to find the location of the terminal block and the right connection. If all else fails, see if your local dealer can copy a page from their shop manual for you.
