How do I remove old one??
How do I open the rear doors so that I can repair the broken door latch handle. I assume that because the loosening the few interior door panel screws didn't loosen the panels, there must be more screws that are hidden with the doors closed. The Chilton manual is useless.
ecm b fuse keeps blowing and fuel pump not working
is it a ground wire possibly,...?? pass.window is not off track, and i can ground it with small j/cable and it does work!! weird.............
Im having problems with my van shutting off when the outside temperature rises past 60 degrees. It tends to start back up after 5-10 minute and continues to drive for about the next 5miles or so and then acts like it sucking air when u press the gas petal! i had the distributer replaced and the fuel filter, but not the feul pump. Please help save this vehicle from being salvaged. Thanks,Chris
I had just gotten on the highway and I heard a snap like something "fell off" the van, but there was nothing on the road. Then the brakes failed (locked up, couldn't depress them). Then the steering wheel also locked up. I pulled over on the shoulder and could barely stop the vehicle with the brakes as it would barely depress; I had to press very hard on the pedal.

Underneath the van, right below the radiator area, fluid was draining out (brake fluid probably) and a long string of rubber was hanging from a similar location under the van. The 2 ft of hanging rubber does not appear to be cylindrical like a tube, but the end on the ground appears tattered, like worn out rope at the end.

Any idea what happened? Broken brake line? Any issue with the brake master cylinder?

Thanks for any and all assistance!
car starts o.k.,[cold] runs o.k., but if driven approx a mile or more to destination,then shut off. After about 5 to10 minutes later can,t start it to return home. Turns over good, but won,t fire up unless you wait until it cools down. Been told might be fuel pump or fuel filter. Do you think they are the problem? Could you also tell me where the fuel filter and fuel pump are located and how to access them. Thank you.
