I don't know what this means, "car discharges dont shift right so i unpluged it the car charges". but did you verify the transmission computer - TCU or TCM - is correct?

If the pump continued to run after shutting off the car you fuel pump relay was probably staying latched. I would replace the relay as well based on your info. Along with the pump the fuel filter should be replaced too and fuel pressure should be checked. Make sure your ground is good also.

Breaker/Fuse block can be located in the engine compartment area, up under drivers side foot area or the passenger side lower right kick panel area.

u are going to have to replace the wiper switch.

Not the torque converter, that would cause slipping. Most likely not even the transmission. Most likely something to do with the ignition. Wires hardly ever go bad, check the spark plugs, the gap on the plugs needs to be a certain distance. Distributor cap and rotor should be dry (on the inside) and clean of dirt/grime and carbon build up. If your mechanic is correct then it should have been the wires, replaced and problem gone. If not, take to a different mechanic, he's filling you with lies.

I'm going through same issue with my 95. Have replaced computer, starter, mass air flow, and fuel pump regulator. So far no luck.

From your description, it sounds like your fan is the problem? I'm not intimately familiar with the pontiac vans but you pretty much need to track down the heater fan motor and the wiring between it and the switch. Check these wires for a fault and/or replace the wiring or the switch or the motor if need be. Because it's an intermittent fault, I think you probably just have a poor connection.

Check all your fuses just in case.

Good luck!
