Cost of a wiper motor assembly for '93 chevy cheyenne 1500, 4.3 v6

TBI fuel injection is 9--13 psi. fuel pressure

When truck is what?

Will it physically fit? yes. Will it be a direct replacement any everything hook right up and plug right in? If we are talking about an automatic then no. 1994's wiring was completely different than the 1997. Can it be made to work? possible, but I believe it would be more trouble trying to make it work than if the correct transmission were located and installed. If it is a cost issue where he has a good trans out of a 1994 he might see if a salvage yard will do some partial trading for the correct trans.

Hello, my name is Ben and I can help you with this problem. This is a very common problem with Chevy. You need what is known in most vehicles as a "pulse board". The pulse board is located inside the wiper motor control module. On many vehicles the pulse board is replaceable, unfortunately on your Silverado you must replace the entire Wiper Motor Control Module which is bolted onto the top of the wiper motor. To get to the wiper motor, first remove those little nut covers on the big end of the windshield wiper arms, if you slip a small screwdriver or your fingernail they just pop off. Now unbolt the windsheild wiper arms, before removing the wiper arms, mark their location on the windsheild with a grease pencil or magic marker. The arms are hard to remove, you need to kinda wiggle and pull at the same time, now that long plastic cowl needs to come off, those clips at the front edge just slide forward, then at each end lift up that rubber flap and remove those TORX screws. Remove the cowl and set it somewhere SAFE, it's easy to break. You will now see the control module mounted on the wiper motor, unplug the electrical connections and remove the TORX screws holding it to the motor. Assembly is the reverse of dis-assembly. If you have any trouble or questions, feel free to ask, Ben.

There is a circuit board in the wiper motor assembly that goes bad. GM had several recalls on various model trucks and suburbs for this problem.

code 12 is always present in gm motor products. it simply means no tach signal because engine is not running. i would go with the simple first and clean the throttle body real good . that takes care of 99% of idle problems.

idling very fast could be vacuum leak or the temp sensor look 4 a bad vac hose or a leak around the intake manifold gasket as 4 the wipers thy are known 4 that when thy git wet i have tried drying them it worked 4 a little wile till i could re place the wiper control on the wiper motor PS.could try some injection cleaner in the fuel i use it a lot 4 the cars that sit around look 4 concentrated or seafoam at the parts store

Sounds reasonable if that includes labor. I just upgraded my 98 silverado injectors from SFI to MFI last weekend. Cost me $350 for the parts and it took me 4 hours.

replace the wiper board, go to your local chevy dealer and purchase the wiper board. remove the wiper motor cover & you'll see the wiper board. be careful not to break to the plastic arm.

check for tune up
check for vacuum leak
