Which fuse is for the rear defrosters on a 1988 Caprice Classic? Owner manual doesn't list it as such.

Which fuse is for the rear defrosters on a 1988 Caprice Classic? Owner manual doesn't list it as such.

the fuse cover should indicate the fuse...it will be 25 or 30amps..

make sure that the wire to rear heaters is not shorted out...if fuse blown...

make sure that the feed and ground is good at heater..if so you have an open defrosting grid ..this can be repaired..
