Help Needed! LBEC Fuse/Electrical outage

[jnorwood]

Good Day,
I have a 2005 Tahoe Z71 today was just out shopping when returning to my vehicle noticed the doors would not unlock. After further investigation, the power locks do not work, the power windows, the radio, shift indicator, several gauges, rear air/heat, and ABS light on.

It seems as if, according to the owners manual, the LBEC fuse is blown I have checked it, and even swapped it out with another 50amp fuse and still nothing. If there is anything you can do to help it would be very much appreciated. I am very mechanically inclined and unfortuonatley can not afford at the moment to take it to a dealer

Best Regards
Jason

Lbec fuse

Check at the battery first and then after you have pulled the fuse check the connections in the fuse box there could be a fusible link that is open....

Thanks for the reply, battery has been checked, truck still drivable as I drove it home about 30 miles. I have gone through every fuse on the truck, as well as checked as many grounds as I could. I am missing something somewhere I just can not figure it out
