1997 trail blazer is there a fuse and where is it located ??? engine pull starts fine but nothing else electrical works

 

20 amp circuit breaker in a plastic pouch located up from the battery,usually on the frame rail area. Usually they corrode from moisture or just burn out over time. Slice the pouch open IF there is no power leading out of the pouch. You can get these at any auto supply for a few bucks.Use some electrical grease on the new breaker posts and tape the pouch up good.IF power is going through the breaker ok,the problem could be in the left control switch wiring or the switch itself.

 

THANKS for the prompt reply
