I have a 1994 Acura Integra and have recently run into an electrical problem. When the radio is on, the antenna won't rise. In addition, the rear window defroster doesn't work, and neither does the intermittent wiper feature. Are these all somehow related?
We've checked all the fuses and they're fine. Not sure if this has anything to do with the problem, but it all happened right after I picked up the car from its 90K mile tune-up in which it also had its radiator replaced.
A technician accidentally cutting wires in just the right place, partially separating an electrical connector or blowing a fuse while making a repair can lead to some oddball problems. I'm not saying that's what happened, but anything's possible.
Double check fuse #3 (7.5 amp), which is located in the fuse/relay box under the dash. This fuse supplies continuous voltage to both the power antenna motor and the integrated control unit. The integrated control unit is an onboard computer that controls the operation of several electrical accessories, including the intermittent wipers and rear defogger.
If fuse #3 is burnt-out, the interior lamp on the ceiling will also be inoperative. And, inevitably, you'll have to find out what blew the fuse so it doesn't happen again. If the fuse is good, it's going to require a technician to begin testing each component individually to see what was lost and where. The problems may be linked, or maybe not. Crazier things have happened.
