Cuts off when making a turn - 1993 Buick Park Avenue

You can not just cut a wire and have the turn signals still work. You need to have the turn signal switch replaced.

Tumblers are not lining up when you insert the key and turn. You might need to call a locksmith. When the locksmith makes you a key, keep this as the emergency backup (kept at a safe place at home) and use the copy made from this backup as your primary key use. When you make a copy from another key copy, the cuts are slightly off. As you make another copy from a key copy, the margin of error on the cut increases until finally, the key cuts don't line up to turn the tumblers, then you're back to calling a locksmith again.

If stock radio it has build up in side and will need to be open and cleaned, if after market, one of the wires is not making full contact.

CHEK ERTH CONECTION

Sorry we have no info on this make, just to few of them on the road.

No, the chip will not cause you not to be able to turn the ignition. The new keys need to be worn down a little to work properly. Over time keys wear down and stop working right. New keys cut in a automatic key maker are normally too "high" for the tumblers in the lock making it hard to turn. You can add graphite to your ignition which should make it easier as your ignition becomes used to your new keys. You can find graphite at Autozone for about 4 or 5 dollars.

If turning head lights on makes the car die,then the alternator is bad.Replace the alternator,and have the battery charged with a slow 2 amp charge,this should get you going.If I can help,let me know.

Sounds like a stuck relay inside the windshield wiper module. It is actually called a "Cover" which is attached to the windshield wiper motor under the cowl.

may be the fuel supply system have some complaint.try to check it.also try to check the ignition system

Get a Chiltons/Haynes manual for your make/model/year and go to the troubleshooting section. It sounds like the same thing my little rabbit did years ago. Turns out it needed new fuel filters and the fuel tank flushed. The gunk kept impeding fuel flow. Didn't do good things for the fuel pump either.
