Car Forum / Honda Cars / January 20051988 Accord Electrical Problem
Hi, My car's radio and heater fan just stopped working at the same time. The radio fuse is okay, I'm not sure where fuse that controls heating fan is - (is it the same as cooling fan?). Does anyone have an idea as to what the problem might be? Thanks Greg > Hi, > [quoted text clipped - 3 lines] > > Does anyone have an idea as to what the problem might be? If the two problems are related, I very much doubt that this is a problem in the positive supply, since the blower and the stereo use separate supplies all the way back to the ignition switch. A guess would be that the ventilation blower and the stereo share a ground connection, and that this connection is broken. Unfortunately I can't find a diagram over ground lovations in the Helm manual. Is the blower dead on all speed settings? Do you have push-buttons for selecting where the air comes out, or is it a manual lever type system? If push buttons, can you hear the little electrical motor buzzing for a bit after you select a different setting? > Hi, > [quoted text clipped - 3 lines] > > Does anyone have an idea as to what the problem might be?

Then I believe it is a broken ground. > Hi, > [quoted text clipped - 7 lines] > > Greg You might want to check fuse #22 (40 amp), located in the under-hood relay box. It feeds both the radio and the blower motor. HTH, Richard >> Hi, >> [quoted text clipped - 12 lines] > > HTH, Richard Where I live it's minus 20 celsius right now but I'll check this asap. I'll post again when tested. |
