2001 Buick Park Avenue

[quote:4e808f31fe="amannpvb"]Buick Park Avenue 2001 6 cyl with 56,000 miles. Check engine light has come on. this happened after a service for oil change, new air filter etc.

the "tire pressure low" warning has been showing for about 2 months. Intermittently, power windows are sluggish but work efficiently most of the time.

Suspect that there is an issue with something electrical although I have been unable to pin anything down. Tire pressure when checked is normal. Battery is OK no drain when vehicle is running. All other electrical peripherals appear to be in good working order.[/quote:4e808f31fe]







You should start by getting the codes for the check engine light.

As for the tire pressure low need to be reset
check pressure in all 5 tires yes 5 tires
(Spare tire check it)

in the fuse box push reset after making sure all tires ok

Good luck
let us know
