1989 Buick LeSabre the windshield wipers will not turn off. How do I get them to turn off please.

You should have a wiper fuse in the interior fuse box that you can pull to temporarily turn the wipers off. I suspect that the issue is due to a bad wiper switch which will need to be replaced.

89 LeSabre start , run like new one drive short or long distance and turn off and won't start back

Hello. It seems either your ignition module is malfunctioning and/or you engine has a case of 'vapor lock'. 'Vapor lock' happens when fuel 'percolates' becomes a vapor instead of liquid; starving the engine of fuel. Of course, the engine won't start until it cools. Good luck and keep me informed; if you want to.

How to troubleshoot air fuel mixture problem on 1989 lesabre

If your car has a MAF sensor, it is in the air intake hose between the intake and the air filter. If the check engine light is on, you would need a scanner to read the computer data coming from the sensors to diagnose the problem.

Why without warning car would not fire 4 or 5 times, then started ok 4 or 5 times, now won't start again

You will need to figure out if you are lacking spark to the plugs or fuel to the injectors to know which system to test.
