fuse 9 keeps blowing
the issue started about a month ago. dash lights/ taillights fuse blew. thought it may be trailer harness, changed out the plug, and checked wires for any bad places. none were found. so, i cleaned the ground attached to the truck. i unplugged the main harness to the rear, and tried a new fuse. it was work fine dash lights work. So, i plugged the rear back up, and pop. fuse blows after a couple seconds. i can't see any bad wires anywhere. i checked the tail lights both worked fine before the fuse blew again. do the plugs ever go bad?
yes....sadly to solve this problem (have seen them before) you'll need a "power probe" which has a tip that you can check for the presence of 12 volts with...you can apply ground with...you can "Juice it" with 12 volts all with the on-board breaker so you aren't starting fires here--- granted they aren't that cheap but this gives you the ability to check any wire and activate whatever can be activated~
My number nine fuse keeps blowing out what could cause this problem.
I will tell all of you the REAL DEAL the cause is a design flaw , the core support panel behind the front amber lights is placed to close , therefor chafing occurs on the amber plug in wires. Solution : put a piece of GM plastic insulator covering around the wires .......PROBLEM SOLVED !
I know exactly what it is!!!!!!! It is the blinker switch. I’ve been having this problem for months. I’ve been searching through the wiring harness looking for a burnt wire. I crawled under the dash and decided to unplug the blinker switch to try something new and it never blew. Something shorted out in the blinker switch!!!! Problem solved.
#9 kept blowing after I was done towing a trailer. Plugged the trailer lights harness and two wires were disconnected and was causing a short. fixed and ready to go
Pulled the trailer lights harness**
If you have the tow kit check the trailer wiring harness ground wire. If there's rust buildup use whatever you need to to get good contact. Fixed my problem.
