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.

When i got my used 1989 Buick Lesabar I was told the cadillic converter was clogged which was causing the car to knock and staul out you could only drive it for a short distance when it would cut off

Bro, This is a model which should get a good attention on all of its parts. You should have a detailed idea on your car's parts, its condition, workability,etc. So firstly try to figure out any kind of leakages from crank parts, gear/clutch assembly. This is easy to find when the car is parked for long time. Then look out for any broken pipes, tubes, seals, cracks. Any oil leakage into combustion chamber, plugs, etc. Check plugs by touching the car body while cranking!! Then check the distributor cables and the distributor. I think this all about your Power lines, fuel pumps. So please try and rate it!!!
