20 Most Recent 2006 Pontiac Grand Am Questions & Answers

What after market products do you have , if any ? Have you done any electrical repairs ? Could be a ignition switch problem , GM has had switch problems for sure . The starting of your vehicle is computer controlled by the BCM - body control module . The ignition switch could be sending a wrong input to the BCM ,causing it to start .Power to many of this vehicle's circuits are controlled by the module that is designated the power mode master (PMM). This vehicle PMM is the body control module (BCM). The PMM controls which power mode (Run, Accessory, Crank, Retained Accessory Power, or Off) is active.
Serial Data Power Mode
On vehicles that have several control modules connected by serial data circuits, one module is the power mode master (PMM). On this vehicle, the PMM is the body control module (BCM). The PMM receives 3 discrete ignition switch signals to differentiate which power mode will be sent over the Serial Data circuits. The table below illustrates the state of these inputs in correspondence to the ignition switch position: If this came to the dealer I work at the first thing I would check is the ignition switch inputs to the BCM . I would use Tech 2 , GM factory scan tool .

Relay Controlled Power Mode
The body control module (BCM) uses the discrete ignition switch inputs ignition 1, ignition 3 and crank to distinguish the correct power mode. Once the BCM has determined the power mode selected by the vehicle operator it will energize the Ignition relay, Run relay and retained accessory power (RAP) relay, depending on which power mode is selected.

good luck !

Is this a trick question? The Grand Am only produced until 2005. There was no 2006 Grand Am.

leave ignition in 'on' position for 15 plus minutes-then, without turning it off, start the car, this bypasses the security system. It may or may not solve it for now, but what is happening is the ignition switch has a set resistance that the security module looks for and over time, as the switch wears, it changes the reading-there are only two fixes, replacing the ignition switch, or snipping a wire on the security module and inserting a 2200 ohm resistor in line to the snipped wire.

have you tried starting it in neutral? May simply be the neutral safety switch?

You need a new instrument cluster my friend. But check with your local dealer first to make sure that there isn't a current software calibration for correction of this problem.

try a pick a part junkyard. Replacement mirrors are cheap, you just have to pull it off a used car yourself. Go to google and type in "pick a part junkyard" and try to find one near you. You may also to be able to find a parts car on craigslist.com that you can go to to get a mirror off of. And ebay may also suprise you. Go to ebay and type in the mirror you are looking for and you may be able to find what you need. Hope this helps:)

If a valve is expose on the upper heater hose piping crack that open only when the engine is warmed up for at least 15 minutes. If no valve is seen you will need to loosen one of the heater hose clamps ever so slowly to let the air out. The process to loosen the clamp is not recommended unless you do this first..... When the engine is COLD loosen a hose clamp and remove the hose and put it back on. Thighten the hose clamp snug only. The start the engine to warm up. In about three minutes see if you can twist the hose to move on the fitting. If you can snug the clamo a lttle more and check again. You do not want the hose to come off if too loose. Now that the engine is warmed up for 10 to 15 minutes shut OFF the engine and barely loosen the same clamp 1/4 turn at a time until coolant trickles out. Listen carefully for air escaping too. Air pressure does built up only when the engine gets hot and the air pocket does not move when the engine was cold with the hose removed beforehand. If no air was released upon this proceedure you have a blockage in your system and flushing maybe the only other option using pressure instead forcing the coolant out. Get a can of coolant flush before the power flush proceedure. A radiator pressure tester can be used to power flush with an air fitting adapter installed in place of the guage

First you need to see if your getting spark to the plugs, then you need to check to see if fuel is getting to the fuel rail.

If this is OK, then check power to the CKP (Crank Position) sensor that comes from the PCM (Powertrain Control Module) and the trigger also comes from the camshaft so the only thing you can test is the wires from the crank sensor connector to the PCM and if good then the problem is on the pcm computer. Some fault codes there?
