What fuse controls the rear window defroster/defogger? My book says it is #15 (30A fuse) in the engine compartment fuse box but I checked it and it looks fine. Trying to figure out why mine stopped working.

Hello,

The fuse is in the interior fuse panel. Here is a guide to help you test the fuses and the fuse panel locations and identifications below. It shows the fuses and what they power

Neither the rear defroster or rear wiper/washer fluid dispenser are working. I have checked on the mini fuses under dash and hood all are good, please advise, thanks.

Can you hear the pump running in the reservoir? If not pull the pump and check for power when button pushed, if you have power the pump will be faulty.

I will try that thanks. Is this all tied together with the rear defroster in the back window its not working either. Also when you press the rear defroster swith it normally lights up, no light at this point. That's why I thought it might be a fuse.

No light indicates no power, check the switch first.

Ok. There are alot of fuses under the hood that are not Mini's. From a fuse perspective, what fuses and what type of fuse control the defroster switch, and rear wiper/pump?
