1999 Gmc Yukon Electric help

[BradyBargo]

Good Evening everyone I have a 1999 gmc Yukon has a power drain over night things I’ve noticed
-Rear HVAC Fuse blows threw the night
Nothing is wrong with rear hvac blower motor everything is functioning correctly

-Power Door Lock, Six-Way Power Seat, Keyless Entry Module Breaker gets so hot can’t touch it in about a hour and seats stop working cause breaker gets hot and kicks out

Any help where to start at would be nice just purchased this thing would like to get everything fixed

When I purchased this thing I had to put a ecm on it got it from a same year Yukon and also had to put the passlock module in it to

Don't know what's wrong with it...but...I think I would be unhooking the battery at nite or whenever you leave it unattended. Do this until you get the problems resolved. Don't wanna burn that baby down !
