POWER STEERING

[justinius7]

I have an 88 GXL with Auto Suspension.

Twice in the past week the steering wheel is stiff at low speeds (as if power assist still things the car is on the freeway).

This happened again this morning, I turned the car off, and immediatly restarted it. The steering was then isuddenly back to "normal". Before turning off the I tried playing with the SPORT/NORMAL swith but it does not appear to fix the steering issue.

Is this possibly a mechanical issue or electrical. Where would i begin to diagnose? Shall I or do I let the system complely fail before attempting to fix it?

I've had the car for 12 years, besides an oil pump and alternator failing, I've had no issues. Oh brakes and a clutch
