Chasing a drain, and the circuit is marked MUX/T Tow on the fuse box cover. Does anyone know what all is on this circuit. 50 amp fuse so it must have a lot on it, I would think. Thanks

 

Resurrecting an old thread, I have also discovered a draw on this circuit on my '98. I have a receiver on mine, but I don't see any provision for factory tow harness. Or does this mean there is a wire lead under the dash for a brake controller that somehow has found ground?

Anyone with a factory owners manual that can look up the items on this circuit, please.

 

looks like dang near every power accessory in the car runs through this circuit, hence its 50 amp rating.

More troubleshooting to pursue...

 

Check the glove box lamp/ switch. Mine was killing the battery, didn't notice it until I drove it at night (I never do).

 

Glove box switch is working properly as is the under hood light and switch. These are probably the only two that are working correctly.

Talked to a local guy about this and he suggested I start exploring behind the kick panels. He said has has seen several of the Limiteds with sunroofs that end up with plugged sunroof drain channels which leads to leaks down the a pillar and damage behind the kick panels.
