Question about 2001 Pontiac Grand Prix

2001 Grand Am DIC slow to light, heater console not working

The issue is intermittent. Sometimes when I turn on the ignition, the DIC does not light up. There is a delay of two to three seconds and then everything on the DIC works and the Service Vehicle Soon light comes on. The HVAC console will not work during all of this. Rear defroster and AC button do not work. Day-Time running lights, head lights, high beams, radio, windshield wipers all work. I do feel hot air coming through the vents, but not fan driven. Replaced ignition and computer in July 2010 with GM dealer flashing the computer. New battery December 2012.

Take your car to Kragen or a parts store like it and have the system tested for codes, also ask them to test your charging system for low voltage, all this is free.

SOURCE: lights go out on dash DIC

make sure you clean your positive battery terminal. It can be quite corroded in there without any outside signs. Next check ground connections (main ground is under the underhood fuse box...is it rusted down there? If it's none of those, start looking at the ignition switch.

SOURCE: 2000 grand prix day time running lights/blower not working correctly

Believe it or not, but it was a bad ignition switch. I the switch apart and found about 3 different and one in particular that were burned pretty bad. Must have been the circuit that controls the blower and DRL? Found the solution on another blog. I put a new switch on in about 1.5 hours. I does take a couple special tools, very small female torx sockets. Other than that pretty easy.

SOURCE: Rear Defroster Problem

1 st of all check all the fuses if all are good it may be the switch itself .......if you are referring to just the defroster ensure both connections are connected to th rear window if there are any breaks in the defroster lines as you will they sell a metal fill type repair kit not expensive and with the use of tape and this mixture you can easily repair the breaks in the defroster lines ........but first ck your fuses and connections maby determine with the use of a test light and check for power at both the switch and the rear wire connections for power to them otherwise it is most likely the switch

Testimonial: "Thank you. There's power at the fuse and power up to the switch is good. No power at the rear tab or grid so I guess I need a new switch."

My heater periodically works in my 99 ingrigue. Super frusturating. When i start it sometimes it works and sometimes it doesnt.


The temperature display and the heater function are likely two different issues. I had a similar issue with intermittent heat on my 2001 Aurora. In my case it turned out to be the blower motor. As a vehicle ages and the bearings on the motor start going bad, the amount of energy it takes to spin the motor gets higher and higher. This can result in intermittent behavior or cause the heater resistors to go bad. It is also possible that the heater control itself is the issue, but with the age of this vehicle, I would start with the blower motor and then heater resistors.

Climate control switch does not work in lower modes only in high.


The pontiacs have an issue with the ignition switch, I have a 2001 grand prix that did the same. The ac fan would only work on 5 and the headlights would go off if on 1-4 replace the switch and all is fine.

2001 Pontiac Grand Prix GT multifunction switch problem?


I had the exact same problem, I changed the "ignition switch" because the contacts inside were burned, this is why you see all those troubles coming in and out at different moments. It costed me 150$ to do it myself, buy the switch on an online reseller, must cheaper than the dealer! Now everything is back to normal on my Grand Prix GT 99 exept that my headlights don't light up automatically when starting the car... I have to check my fuse/relay and switch to make sure everything is ok on that side.

Good luck.

2001 Pontiac Grand Prix GT multifunction switch problem?


The multi function switch is the turn signal switch. It also does control wipers and lighting. If you are having the issues you describe then you will most likely have a body control module problem. Before you spend the money to buy the module and get it programed get it checked first. Goot Luck
