When we go to the information tab, it will not give us the speedometer information. We recently had new tires installed and noticed this after. Would our dealer be able to solve this problem. We have not had this problem before.
Was backing out of my house and the entire car shut down. Had two micro relays that were burned out. The power train relay, and the ignition 1 relay. Still have no power period.
Lately my car has been overheating a lot it's only overheated to the point it shut off seems that when I press my gas pedal to hard or when I'm driving between 30 mph to 60 mph it overhears more and it'll cool itself off randomly under 30 or when I turn my wheel to the right and sometimes when I press my brakes I haven't found any leaks and the only sound I hear is the fans when she's overheating bad enough the system shuts off my a/c unit
My 2011 buick lacross, I just bought it and for some. Reason I tried to hit the power button at night time it does light up and so does the auto button for the heat and air panel but for some odd reason there is no air blowing out at all, my husband took to this electrical place they said the blower moter was fine and they didn't know what was wrong with it. If someone knows whay could possibly be wrong with my vehicle can u please let me know I have 3 younger children it's getting very cold outside and I have to have heat in my vehicle. Thanks so much
