2000 Pontiac Grand Prix keeps blowing fuse po412, po418, po443

When the fuse blows it causes these 3 codes to happen. Some times the fuse will last for a few weeks and other times it will blow right away.

    also has codes po102, po135, po141

    When the fuse blows I'm getting a total of 6 codes. The only thing that does work is the MAF so the car seems to run fine except a little surging sometimes with the tack. I actually get a little better gas mileage with the light on. The only other problem is the car will run a little warm when you have to pull mountains and run the A/C or if the temp is over 95.



    Thank you!

i have an Idea. first of all make sure that all of your vents are not plugged up. next check your heating coils to find out if only one side is hot or the other is only cold. i need more info

SOURCE: How do you relace a heater coil in 2006 pontiac grand prix?

I don't want to over step my knowledge but you car is only 3 or 4 years old. I don't think your heater core is bad, unless it is leaking, Sounds like you have a blend door problem in the HVAC system. This door is actuated by a servo motor switching from hot side to cold side. This little servo can go bad and need replacing. Just make sure you don't have any bubbles in the coolant system first as long as you havent done any thing with the coolant system you souldn't have any air in the system Hope this helps you. Please rate my solution for you thank you

SOURCE: ac vent problem

Damper/flap for driver's side is probably stuck. Try moving the selector from cold to hot several times. Also, move the recirc/outside air control if the previous doesn't work.

SOURCE: a/c blowing hot air. 3 out of 5 vents are blowing.

With regards to you a/c not blowing cold there are several faults that could cause this. Your compressor may not be working, they may be a restriction in your A/C lines, your compressor and/or evaporator may be clogged, you may have a leak, or i could be something as simple as fuse.

SOURCE: Car Heater Not Working - Blowing Cold Air

also check to see if tube that runs your climate door is not pinched or broken. the vaccum tube that runs the climate door is behind and under the battery. i had same problem a year ago and the tube was partially cut. i fixed it by cuttinga piece of aquarium tubing and spliced it back together. one other thing.....check to see if your radiator over flow cap is tight. your cap maybe bad and or cracked this would also cause the problem.

My 2004 Pontiac Grand Prix gt keeps blowing the 30a fuse for the blower motor resistor wondering why it keeps blowing after replacing the resistor I've went through 4 of these fuses


Possible blower motor is defective pulling excessive amperages causing fuse to blow continuously regardless if its still operable.

2008 Pontiac Grand Prix blowing the MAF/EVAP fuse. Unplugged MAF and still blows fuse. Let vehicle sit and cool and it didn't blow it again. Plugged MAF in, cleared codes and drove @ 15 miles and it blew...


Replace the EVAP purge solenoid. It is powered off the same fuse and it works as you are driving and not at idle . The MAF sensor is working all the time the engine is running.

Are you saying the fuse blows when you turn the key switch on ?
Could be a faulty injector, or a problem in the wiring harness, even the computer could have an internal short.

My 2000 pontiac grand prix 3.8l keeps blowing the fuel injector fuse pretty much everytime the key is turned on


Might want to chk. for a bear wire on the injector harness that might be grounding out, or might be pintched, if its had engine work done on it in the past. Also chk.wear the injector harness plugs into the maine harness too.
