Re: front wiper motor not working
Disconnect the negative battery post.
disconnect the harness from the wipper motor, using a 8mm socket, loosen the two crank arm socket screws and lock-washers until the socket releasesfrom the crank arm ball. do not remove the crank arm from the motor.
using a 10mm socket, remove the three motor retaining screws, slide the motor out of the slot in the bracket.
To install make sure the wipers are in the park position, slide the motor into the slot in the bracket. using the 10mm socket, install the three motor retaining screws and tighten to 49-80inch lbs.Using the 8mm socket tighten the two crank arm socket srews and lock washers. connect the harness to the wiper motor.connect the negative battery cable

If the motor is working, the linkage between the motor and the wipers has broken. I don't have a Venture, but usually there is a plastic panel below the windshield, where the wiper arms are mounted. You remove the wiper arms, then remove the plastic panel (might be screws or it might just snap out) to get at the linkage and motor. Dealer or auto parts store should be able to order new linkage arms for you.
Look online for the wiper module for this model. This is a common issue to include operation without the switch being activated. Everything is controlled by the module which screws directly on the front of the wiper motor by 3 torx head screws and measures about 4" x 4" and is very easy to install. The motor should be on the firewall. The modules run anywhere between $35 and 65. Let me know if you need anything else.
The wiper linkage and blades should be in the neutral position, or where they would normally lie when in the "off" position. Hope this helps. Remember to disconnect the battery while replacing electrical components.
I found problem to be that corrosion sets in between the CAMS plates
that circle in an opposing fashion and does not let the wiper arms park
correctly. Be very careful with this mechanism if you have the cowling
TURN the KEY and WIPERS OFF and watch your fingers so you don't get them
WARNING if you leave the power on and try to move the arms This cam
mechanism springs to life and will try to self park the wipers on their
own so Turn the Power and Wipers Off.
1. With the ENGINE COLD, Spray a lubricant that FREE'S CORRODED PARTS
like WD-40 between the gap of the 2 CAM Plates and on Top of the plates,
or use some other automotive parts lubricant that free's corroded
parts(let it soak for 5 minutes).
2. Gently Try to manually move the arms back and forth a little bit so
that the spray works into the parts.
3. This may not be necessary but I had to do this the first time.
There is a notch in the top cam that has a STUD that locks the 2 CAMs
together. You can push on this STUD to unlock the cams by manually
moving the wipers(use a screw driver to push on the STUD and have a
friend gently move the wipers manually. Spray the area LIBERALLY with
with the Lubricant Spray and see if you can move the CAMS back and forth
and work the lubricant in.
Then with the wiper cover out of the way and all tools clear Try to
cycle the wipers HIGH and LOW, ON and OFF a few times it may stick the
first couple times with the wipers in the up position but I am confident
that the lubricant will work its way in and free these CAMS the way
they are supposed to.
Your wipers should self park after cycling them after 5-10times. This
should solve most of the problems with these
wipers and should be relubricated as needed. Clean up any extra
lubricant Put the wiper cover back on.
I will give you my honest opinion here. Goto Autozone or any other local parts store and get the Haynes Repair Manual (around $15). Follow the directions in there. Its the best book you can buy for your car and save you alot of money on labor for things like this. I have done a few of these myself and its a decent afternoon project but its easy enough that anyone can do it following the Haynes manual. Good Luck to you.
