Question about 2002 GMC Savana
Hi Jim, If the vehicle is fitted with climate control it will have electronic management. However it can be wired by someone knowing electrical circuitry to by pass the control. It will save you some cash but will need manual control. Make sure whoever does the job knows what he or she is doing. Have a happy new year. Regards John

look under the hood on the right side where your brake fluid is..There is a black box to the farest right of the brake fluid. take off the lid to this box were you will find fuses..Reach in and feel the fuses to see if any are loose.The largest fuses in the front, push down on those and then try to start it up..Take them out look at them make sure there ok if this dont work..they the one bad might need to be replaced..

More than likely this should just be your resistor. You have different sized coils on the back of your resistor for all the different fan speeds. if one of them burns out or breaks then that certain speed will not work.

Yes, definitly the blower motor resistor. Usually located just under the dash on the passenger side. Usually a result of mostiure entering the compartment where the resistor is located. Very common issue actually.

The manufacturer does not even publish a troubleshooting chart for this. (At least, not a chart that is not associated with a computer fault code)
Most of the things that will cause your vehicle to not have spark will also cause your engine to not receive fuel. (no injector pulse) The only things I can think of would be a bad ignition coil, or a bad distributor cap and/or rotor, or a bad ignition control module. Depending which engine your van is equipped with, there should be an ignition control module located near the ignition coil. I would check for spark at the coil. If there is spark at the coil and no spark at the plugs, replace you cap and rotor.
If there is no spark at the coil, it could be caused by several things, but if you are certain that you have injector pulse, the most likely would be the module. (coil failures do happen but are more rare)
