2000 Buick LeSabre Electrical Problems + Blend Door
I'm Trishanna and I just inherited a 2000 Buick LeSabre Limited. I need some feedback and ideas from some experienced owners or mechanics on this beauty. It has some quirks that I'm trying to figure out what is going on. I am pretty savy but this car has me baffled.
Quirk #1 = I noticed a couple days ago that the car has no back up lights, license plate lights, or lights on the trunk. I first checked bulbs and replaced if needed. Nothing new. I next checked fuses both in engine compartment and under back seat. All looked good. No change. Next I took a tester to the plug inside the trunk. Positive for power. Then checked the individual sockets. Positive for power except the reverse lights. Placed vehicle in reverse, still no change. Replaced bulbs and still nothing. Help!
Quirk #2 = The car inside temp is always hot on driver side and cold on passenger side. Figured it may be a door in the system being stuck open or closed. All gauges read normal so not likely a thermostat issue. Boy does that Auto temp system blow especially to whomever is in the passenger seat.
Quirk #3 = The heated seat on the driver side lights up on the switch but doesn't warm the seat. Any ideas?
I pulled and checked every mini or maxi fuse. Don't know if it'* a relay that'* bad or something else for all of these issues. The previous owner was like a great grandma to me, and she always had work done by an authorized Buick dealership. Within the last couple of years, the car had a new fuel tank put in, rewiring of the back end due to rodents chewing things up, significant break job done, new battery cause she kept leaving her lights on. Any help would be much appreciated.
