Hi All


Any know issue with a 2009 Tahoe where the drivers said Parking light fuse continues to blow.... time frame for fuse to blow is variable and not consistent...sometimes its days or weeks ....and sometimes its instant.....it's a 15 AMP just for the marker lights front and rear drivers side....

First I've heard of this. I'd start by looking for a wire sorting out to the body.

I'll look funny thing is last year when it got cold here it didn't blow for months....

When things get cold they shrink up , its possible you have pinched wire and when its cold everything is contracted and the short does not happen, things get warm and expand and now the wire is shorting to the grounded pinch point....
Pull the lamp housing and check the wire harness as far back as you can to the fuse box until you find the pinched wire(s)

Anyone have a wiring diagram so it makes it easier.....
