hi the contacts in the switch would appear to be faulty if you can get to the switch try spraying the switch with wd40 or simular as if you can spray the contacts it may clean them if you want abit more positive diagnostic while wipers are working disconnect the wires from the switch when they won,t turn off if they continue to work check out the relay yates210456

Need to check your coolant level, that is the first culprit...It has to be full in order to circulate in the heater core...

It could be a clogged fuel filter or a bad fuel pump. Also try replacing the spark plugs and spark plug wires and having the timing checked. Good luck.

could be a bad fuel pump, or fuel pump relay. they are having problems(a lot) with the ethanol in the gas on GM products.Fuel pumps sales are through the roof at parts house on GM's. Have a pressure check on your fuel system. That is probably it. Add a can of Seafoam to your fuel every 3000 miles to alleviate this problem.
