Inner markers and wipers

I'm not sure if these are tied into one another, but before we swapped motors, we cleaned the sprayed down the engine bay of the old motor so we wouldn't be working so dirty. I think at that time the inner markers still worked until we yanked the motor, put the new one in, then they stopped.

The outer markers still work fine, along with their signaling so I'm not sure whats going on. Are the inner and outer bulbs wired up from the same source for the "marker" illumination?

Second, did we kill the wiper motor by spraying the engine bay down? They still work but they won't park unless the wiper arms are already close to their resting position. Otherwise, the wipers just stop where they sat when I turned them off so I have to turn them back on, let them come down, then turn them off for them to park. Motor issue or switch? Something else?

The wiper thing happens to me too whenever I degrease the engine. Last year at CJ I was joking about how I swore never to do that again because it would be a week or two before the wipers would work normally again. I figure it's a short, but who knows...

The Sport had that wiper problem as well before the engine swap,but afterwards,everything was great.I think the Sport was on the verge of suicide before I got it,and had no hope of living right after I bought it,now,she knows there's something to live for.LOL.

Inner markers are a running light only, no signal(yeah they gave a dual sided bulb, why I dunno)...

Nothing common to the two problems.

Yes, all the parking light bulbs are wired to the same power source. A brown wire brings the power to both inner and outer.

Yes you may have caused the problem if you sprayed into the wiper motor. The motor itself is obviously good. But, there are contacts in the motor assembly that power the motor to the park position after you turn it off at the steering column stalk.

I'll test for power at the inner markers tomorrow and check their grounds - the outside ones illuminate perfectly fine which is the weird part if they are indeed wired together.

As for the wiper motor, I can't guarantee it didn't get a dose of water. I was just surprised they WILL seat if the blades are down low when I turn the switch off.

Also need to air out one of my headlights that got moisture buildup when they sat in the garage for a week - no idea why. Kinda a pain to put back in though when I have to hook up the igniter cable in the little space between the projector and car metal. At least I can also get the nut out of the way that I have to also put back on to the header panel - the one that hides in front of the battery.

The wiper switch may clear itself up if you let it run for awhile.
They have sliding contacts that move with the wipers.
