I Own a 2000 Grand Prix GTP and the transmission began acting strange 2 days ago. It will not engage on Drive or 3rd gears but it does in 2nd, 1st and Reverse. It didn't give any signs of problems before this. I'm thinking that it could be the selenoid but don't realy know. Can anyone offer some assistance?

all the time

The heater only seems to work if I'm driving down the interstate. Idling, or driving through town, the air blows, just never gets warm. We've replaced the thermostat and that didn't help. So now we're at a loss. HELP!

Why do my windsheild wipers rest in the up position when turned off

Driving on freeway, went to pass a car, my car went down a gear to 3rd passed the car & my car never went back to 4th gear or overdrive. All other gears work good, fluid level good. Still able to drive, just runs at higher rpm, been like this for 2 days now. Service eng soon light came on about 5 miles after losing overdrive, connected ETHOS scanner, got P1870 code (transmission component slipping), cleared code, light went & stayed out, still have problem. Have 215000 miles on car, tranny rebuilt at 108000 miles. Suspect internal problem?

how do i fix my air and heat control i cant change it from it from vent.it always stays on vent

when you start the engine it idles fine for 2 to 3 seconds then shuts off. if you rev the engine up and down at 3 to 4 thousand rpm you can keep it running but if you hold a steady throttle or let it idlr it dies. It dosent miss or smoke and i havent found any obvious vacum leaks and i have changed the maf sensor and it dident change anything.It is a supercharged 3800

i noticed about a week ago that my car did not feel as warm as it use to. there was not enough heat coming out of the vent to keep me warm. but enough heat was coming out to melt the snow off the windshield. i am not sure whats going on with the heat in my car.

About how much fuel is left in the tank when the Low Fuel Light comes on?? Thank you
