Speed sensing sterring?'s

I recently got a 97 Towncar. To have it registered I had frt end work done, new tires and an alignment as well as new shocks all around. That tells me steering linkage is good. I drove it 3000 miles on interestates to get it home. No real problems, steering seemed very sensitive. The other day when correcting for a wind gust I was wondering into oncoming lane then into ditch before finally getting control. The speed sensing switch on dash dose not seem to make any difference no matter where I have it. It seems to stay on slow speed sterring all the time. Any ideas?

If I would guess, either the gear box or the sensor that controlls the steering. Its located on the back of the power steering pump.

The more pwr steering pressure, the easier the steering!

There's a valve in the pump that could go bad, but I would try flushing the pwr steering system, and go with some fresh fluid.

The viscosity of fluid is probably bad after 13years.

True. This could be the problem, how ever. With mine I noticed that the gear box did the same thing that his is doing...

Thanks for the replies, I'll keep you posted.

I am a start with the simple first kind of guy and I did not look forward to changing the steering box. I did flush the system three times so far and did notice a marked improvement right from the start, it got progressively better each time. I have been using the car to commute (80 miles return trip) to work since and am pleased to say it seems OK. Thanks
