1986 Dodge Ram V8 Two Wheel Drive Automatic
This is an old beat-up D250 farm truck, so I don't want to do anything other than mount a 3 way switch to run the wipers on low & high. Wiper motor works when power is put to it, and I have checked for bad fuses/relays, etc. There is a plastic relay of some kind I removed from the wiper motor.
I also have my son's 1986 Lebaron Town & Country with the same issue. I have included pics of:
1) & 2) the motor from the Town & Country, where pins are, where relay(?) was removed.
3) the plastic relay(?) from the T&C's wiper motor
4) the same relay(?) from the D250 truck.
The truck's relay(?) does not have the melted resin the T & C does, but does have a small burn mark in the housing on the lower right (of the picture) corner of the resin-covered opening.
Whatever this plastic part is, the people at the parts store said it was a dealer-only part, and the dealership said it was a discontinued part. If this is a typical failure in the part, I don't want to get more from a junkyard that will likely just go bad within a short time...
Question 1 - is this an actual relay, or something other?
Question 2 - is there any harm in running a 3-way switch to operate the wipers?
Question 3 - any suggestions as to which pins to run power to in order to get the most benefit from the 3-way switch?
I would assume (dangerous, I know) that, of the 3 pins that are not grounds, one would be intermittent, one would be low, and one would be high. With a 3 way switch, bypassing the relay(?), am I right that the intermittent setting would not work as such?
Any other suggestions would also be appreciated.
have the same problem?
