2002 Olds Intrigue ...sometimes the wipers start by themselves with the switch in the off position. The only way to shut them off is to push the washer button.(sometimes takes 3 or 4 tries).-do you think the trouble is with the switch or the pulse module?

there is no connection between the ignition switch and the shift lever. One turns the power on to run and start and the shift lever prevents start until neutral or park is set . Therefore it is possible that the fault is not in the switch but in the adjustment of the neutral switch on the transmission.

Replace wiper switch or bring it to your dealer.

Could be a relay or a faulty switch. Have you checked the circuit coming out of the headlight switch to see if it is powered with the switch in the off position ?

Perhaps you might try removing the wipers at rest position (where ever they stop) and setting them back on as close to the folded position. If that doesn't solve the problem it might be in the switch. The last and worst scenario is a defective motor

My best solution, which you may not want to hear is new wiper motors. It seems like a common thing in these cars (the wipes don't go down all the way.

Probably an ignition switch:

hcmartini - did you mean you replaced the ignition switch behind the ignition key? How much would that cost?

you need to replace multi function switch

I have a 99 olds intrigue 3.8l Autozone computer states poor electrical connection or short circuit, or failed vehicle spped sensor or drive gear mechanical fault. speedometer works sometimes and drives great next time it raises rpm and speedometer does not work. Where is the speed sensor or where is the elctrical circuit I can check to see if connections are good.
