Buying a 94 dodge cummins 2500
 

Ok so I'm looking at buying a 94 dodge 2500 cummins reg cab long box it has the automatic trans and 236000 miles the guy says the computers going bad behind the dash that controls lights overdrive and shit like that would anybody that knows about this problem says its a hard fix or costly?any info on truck/computer that anybody would want to give chime in at anytime thanks

there is no computer under the dash. the pcm is under the hood on pass side behind the airbox. what makes him think the pcm is going bad. if the crank sensor is going bad on the 12v it will throw everything off

Dash lights and brake lights are going out sometimes but work others they work other times he did mention something about the bulbs r blowing to he took it to autozone and they said it wasn't a short it was a computer going bad and he may have said it was behind air box I think either way but the overdrive isn't workin sometimes either he wants 4500 Obo but is flexible since he figured out this problem what do u think on it

Body's still really nice other than paint burnt off no rust tho its 4 wheel drive

the pcm would not cause bulbs to blow. and from experience, I wouldn't trust a damn thing anyone at a parts store says. they will try selling you spark plugs and wires to tune up the truck if you let them.

I know headlight switches are an issue might be a couple of things going on like a crank sensor causing the overdrive problems and a headlight switch causing the light problems. :humm:

Ain't that the damn truth....:s:

The TPS could be going bad and messing with the overdrive.

Tps for sure. Idk about the lights. Tps run about $200
