I am trying to find an intermittent wiper (park) relay replacement part. Would I have to go to a dealer for this or can someone tell me where I might be able to locate one for my 99 marquis?

Should be under the bonnet (hood) where all the fuses & relay's are.

Part should be less than $50

Yes, you should be able to replace it yourself once you have located the correct relay.

Likely the relay is the problem, the multifunction switch can fail as well.
I have the troubleshooting diagram for electrical on Series 1 Discos but a very good working knowledge of electrical circuitry is necessary to use this info.

Why won't my windshield wipers turn off. the low intermittent wiper setting is always on

The off switch is actually inside the wiper motor. When you turn off the wipers from inside the car it sends a signal to the wiper motor to park position. Once it's parked it shuts off the power to the motor. You need a new wiper motor.. Sometimes you can get replacement parts. Check with the dealer to see what's available or try a junkyard to save some money.

The wipers work intermittently and I've been told I need a new wiper relay switch, but having problems locating one. 1998 Audi A4 1.9TDI. Have removed existing relay switch and it's 12V and 70A

The only place to get a wiper relay is from an Audi dealer. However, I have that same problem and the relay didn't fix it, I'm still trying to figure it out. I would try the relay first though, it's about $60 I think.

Wipers won't stop wiping.

Sounds like your intermittent wiper circuit is defective. Normally the intermittent feature is engaged by one of the functions on the multi-function switch (usually on the steering column). The circuit of the intermittent wiper periodically activates a relay that closes across the "Wiper On" switch. Your intermittent wiper circuit is likely defective and holding its relay closed (or the relay is stuck closed), thereby keeping the wipers on. Note: The wiper motor has an internal switch that opens when the wipers are in the park position and that is designerd to stop the wipers in the park position. When you turn on the wipers (or the intermittent relay is closed), the motor's internal switch is shunted such that the wiper does not stop at the park point of the cycle.

Wipers do not work in intermittent position. They do work in low and high speeds but do not automatically return to the park position. They stop wherever you turn the switch off.

i belive that your wiper switch has gone out on the intermittent side. this is a very common problem.
I hope this helps you
