Heater fan wont blow on any setting on 2002 gran prix pontiac?


There are fuses for hi and low blower fan inside the interior fuse panels I know the high one is on the passenger side and believe the low is on the drivers side tho they may both be on the passenger side read the cover after you pull them off easy to find once you read the label if those are both good then its probably the blower resistor, fuse check first.

Instructions for installing a resistor for the blower motor on a 2001 pontiac gran prix


Its a straight forward job, the blower resistor is to the left of the blower motor and will have 2 screws holding it in. The blower is just above the passengers feet.

2002 gran prix Head lights come on when blower is on high


Sounds like a bad ground connection to the blower housing. Try to eliminate this by connecting one 'battery jumper cable' from the ENGINE or battery (neg) to the blower motor housing. You may have to get clear of some plastic to reach it. Does this change how things work?

2002 pontiac grand prix-heater a/c blower only works on high


When the blower motor resistor goes it will still usually work on the high setting because that bypasses the resistor.
First look on the passenger side below the glove box you will see 3 press-pins. You need to remove the 3 press-pins and the panel they are holding up.

Now you will se a bracket holding a bundle of wires and 2 vaccum hoses on the left side of the blower motor see pic. This is held on with 2 screws. Remove the screws and let the bracket hang off to the side.

Now remove the blower motor there are 3 screws to remove the blower motor a plug-in and a black hose. The black hose and plug-in you can not see from this side. You will kinda have to angle the blower motor and push the wire bundle out of the way to remove the blower motor.

Now with the blower out of the way remove the closest screw from the blower motor resistor. Disconnect the plug in from the resistor and carefully slide the assembly to wads you and it should pop down. There are a total of three screws that hold the resistor in but you only have to remove the one.

Now just reassemble the way you took everything apart. Hope this helps. I think the resistor is only like $20.00 at Auto Zone or Parts Source, they also have step by step instruction to.

Good luck

How do replace heater core in 2002 Pontiac Gran Prix


i do believe you have to take the passengers side dash apart behind the glove compartment. go to autozone and get a manual or go to the library and check the chiltons manual. this is not an easy job. how bad is the leak? if its not bad these heater cores are made of all aluminum. i would buy a bottle of that radiator additive and see if that takes care of the problem first. it only cost about 5 bucks a bottle and it may permanantly fix your problem.
