The broken shaft on the hyd. Pump controls both the brakes, which I had next to none, and also the power steering.I was able to steer to the side of the road very gingerly, only because at that time I was coasting at about 10mph, almost in front of our driveway.at this time I was towing our travel trailer, returning from vacation, from the West coast, via interstates and many mountainous roads.god help if this would had happen at the time.after unhitching the 24ft. Trailer, our van was flatbedded to our dealer who did a fine repair job on the hyd. Pump problem.as for the wiper control module that is another story. The problem occured in rapid city N.D. while traveling 65mph along a highway, during a rain storm. They just quit operating without warning. We sat out the storm, then proceed back to our camp ground.we located a GMC dealer in rapid city S.D. who repaired the problem. The service manger had told me that this is a problem on many vehicles and keeps many on the shelf.
