Question about 2000 Pontiac Grand Am GT

2 Answers

I have a 2000 pontiac grand prix with a 3800 v6 in it! For some reason the temp barely peaks over 180! The blower motor seems to kick out lukewarm air. the switch doesn't work on 1,2,3,4! It does work on 5! Any solutions would be greatly appreciated! I just want more heat!

Hi, check your thermostat. The stock number is 195 degrees. See picture below for location of thermostat.
On the blower, you probably need a resistor. That is the usual problem when only the High setting works. The resistor is way in back next to the firewall. Picture below is a bottom view of the heater box.

Please see my tip at http://www.fixya.com/cars/r5929960-s_thermostat . These are generic instructions. If you get stuck or need specific instructions for your car, please get back to me with model, year and engine info.

I have a 2000 pontiac grand prix gt 3800 v6 that is not supercharged.i got to get a new engine.will a supercharged 3800 v6 hook up to my none supercharged engine


The engines are the same dimensions and use the same mounts, but the wiring and sensors are a bit different and you need the computer and gauge cluster out of the supercharged car.

2000 pontiac grand prix,heat/ac does not blow out...when it does its for about 30 sec. before it shuts off again,also it only comes on at 5(highest setting)


this could be one of two things .1 a bad blower motor resistor .2 a bad blower motor. if the blower motor resistor is bad i should work on high all the time.
