Question about 1999 Mercury Grand Marquis
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?
SOURCE: intermittent/park relay
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.
