Where is the fuse for my heated mirrors, the manual don't say:banghead: Please help

Is it only your heated mirrors that are not operating? I've never experienced that problem before but I highly doubt that the mirrors have an independent fuse. Let me do some checking and I'll get back with you.

Well, the button doesn't light up and the mirrors dont defrost, so I assumed it was a popped fuse.

you don't say what year truck but look at Fuse 2...check the connection at the heated mirror switch...switch could also be bad.

It is a 98 dodge quad cab. other then by the driver side door, where else are the fuses to check

there are some under your hood.
