just got 05 LeSabre a wk ago. didn't pick up on it @ 1st but radio doesn't cut off nor headlights ding when left on sometimes. Oreillys said may all be linked to ignition switch which makes sense. I would think a sensor in door jam maybe but I've no idea. TY 4 help

2005 Buick. Lasabre cold air is blowing when the heat and defrost is turned on. Even after the car has ran for 15mins. First time buick owner. Need specifics on what auto parts to purchase to keep the car performing.

O2 sensor crankshaft sensor ,tried to start backfired would not run

Over the summer the blower motor would come on and then turn off whenever it wanted to..It does the same with the heater but now only cold air and leaking antifreeze,what could it be?

Vehicle has Auto Temp Control. Blower will change speeds but will not turn off completely. Circuit has 30 amp fuse but no relay. Is problem in control panel or blower motor resistor ?

And the car is slightly rumbling & when I drive it if I sit somewhere for too long like at a traffic light for example it shuts off then I cut it back on & it starts again

I am only getting air to come out of the front vents of the dash. My blower speed works fine. I can switch it from hot to cold no prob. Had one mechanic look at and he replaced the blower motor which did not fix problem but another story as I was pissed they ripped me off as it did not fix problem. Any quick fixes that I can possible do? Pep Boys said bring it in but will cost $45 diagnostic first.

02 lesabre custom. Started with intermittent running, after hitting bump or dash would start again. Heat/cool air works but isnt circulated by the blower, just seeps through Vents. Replaced resistor, tried on new blower motor with new resistor. No results. Fuses/relays look good. Any idea what ear to check? I'm freezing here...

don't matter which mode cold air only when any form of heat is used .cold on driver side

trun signail stays on ,on the left side and will not blink

Window got stuck down window behind that one stuck up and only can control all window from driver side now only control two windows
