Look in one of the rear door jams of the car. There should be a plate that has tire pressure settings for different tire sizes. Verify this pressure against the tires rated max pressure, it is on the sidewall of the tire in very small print. If the recommended pressure does not exceed the max pressure, fill it to that pressure. If it exceeds the max pressure, only fill it to the max pressure. This should be checked and filled with the tires cold (ex. before driving any substantial distance)

If it a serpintine belt (meaning one belt runs everything) and it comes off on its own its time for a new belt to install new or reinstall old one . All cars have abelt routing diagram if not google your car and year asking for belt diagram. Locate tensioner usually turns with wrench ( socket or box end is best) route the belt according to dia. leave tensioner for last rotate pully with wrench to get belt over release tension on wrench thats all there is to it. But if belt keeps coming off usually indicates new belt is needed could also need tensioner pully its a good idea to replace both at the same time

Your problem looks like there is no 4th gear
One thing you could do is :

1. Drive your car at a steady speed and cruising while your right foot is on the gas pedal with your left foot just touch a little bit the brake pedal just to release the brake switch and look the RPM should drop of 300 to 500 rpm in 3th gear. If so, you have the TCC (Torque Converter Clutch) applied next.
2. Retrieve the engine code with a scanner to see if there is any faulty transmission or engine code.
3. If you have code register than you have to solve the code first.
4. After the fix is done erase code so the PCM (Powertrain Control Module)will reset to normal.
5. Test drive to see if your problem is solved.
P.S.: Transmission fluid is very important. Do a transmission flush if you doubt.

Hope it helps.

Chances are it is an electric contact inside of one of the door latches not making good contact. The BCM is getting a signal that one of the doors is being opened and thinks the car is being stolen. Usually ends up being the drivers door as it is used more than the others.

Could be air in the cooling system , try an bleed the system . On top of the thermostat housing is a bleeder valve , with the engine up to temp. open valve till coolant comes out . Is the coolant full ? What color is the coolant ? Have see where coolant turns like a muddy color an clogges the heater core an engine coolant passages . Check the heater hoses going into the fire wall ,are they hot ? Does your grand prix have manual or automatic climate control ? Duel zone ! Do you hear a clicking sound behind the instrument panel ? Bad temp blend auctuator .

You need to get a code reader from an autoparts store to see why that light is on.

If the aftermarket deck has a amp wire you will have to wire it into the lead that controls the amp relay. You will have to get the schematic for your electrical system to locate the 12 volt trigger wire for the relay that turns on the delco/bose amp. that way everytime you turn on the deck the amp will also turn on.

The vacuum switch is right behind the mode control knob on the climate control panel, but make sure it is getting vacuum from the engine before replacing it. There is a vacuum line that goes from the engine intake manifold through the firewall to the control panel. This line may have come loose from the engine, which is the most likely cause of your problem.

The problem is most likely the ignition lock cylinder, there are two tiny wires coming out of the cylinder that break over time. You can replace the ignition lock cylinder or you can bypass the system. If you want to bypass the system, use an ohmmeter to find the resistance across the chip in the key. Then go to Radio Shack and purchase a resistor of the same resistance value. Wire this resistor across the two white wires coming out of the steering column under the dash. These white wires are encased in orange insulation where they come out of the column, then break out of the insulation near the connector.

First guess will be a loose connection on the pickup unit. On the fuel tank it should be undre the rear seat depends on your car. There you can check and clean the connection and check behind the guage on the cluster for any wire or curcuit damage

Minus 35 ? Where do you live ? Has it not ran since then or has it done this more than once ?

Generically speaking, if the compressor is really running and there is no pressure difference, the compressor is not pumping it has gone bad. BUT, since you say it is not cycling off and on, I believe the compressor is not running but you are seeing the pulley turning only. Also if the pressure is 25 psi, it is too low as in the amount of refrigerant is low. Check the pressure switch to see if it is open or closed electrically. Not sure what the 30 amp fuse powers since you say it worked before. Start here.

Make sure radiator is full and that all hoses are ok. Then make sure that the thermostat is opening and that your water pump is circulating coolant through the radiator which must not be clogged. Till you find issue run your heater full blast with window open to add additional cooling to engine.
