hardtop wiper noise, etc.
 

Ok, here's a weird one. I have an 03 Wrangler with a hardtop, got it
new 3 months ago. During that time, I have noticed something odd about
the rear wiper on the hardtop. Sometimes after parking several hours or
(most often) overnight, when I fire up the Jeep, there is pulsing noise
coming from the wiper motor assembly on the hardtop - this is without me
touching the on/off switch for it. It sounds like I imagine it would
if someone had grabbed the wiper while it was on and the motor was
fighting the resistance or something. But, it is unhindered, and - more
importantly - nobody has turned it on.

What I usually do is to go ahead and spray the back window and run the
wiper for a few seconds, which seems to shut the thing up.

Anybody else have this happen to them? What are your guesses as to what
is happening and what I should do to fix?

- thanks!

Re: hardtop wiper noise, etc.
 

I don't think it's your hardtop. My 03 does the same thing on start up,
that pulsing noise, with the soft top on and the hard top on, it seems to be
louder when it is warmer out.

anybody have an idea what the noise is?

Re: hardtop wiper noise, etc.
 

That is a strange one all right.

Maybe it isn't going all the way off when it parks? Likely you have two
12V power wires going to it, one for run and one that shunts over to a
ring plate so when the arm moves to park, the plate falls off the
contact and it parks. This line has 12 volts in it with the switch off.

Is the blade touching the window frame or anything when it stops?
Thinking that might be holding it almost contacting so it gives some
surges like it is trying to park.

Could also be that the motor wasn't put together right too. Maybe the
park ring is just too close to the contact.

Just a couple guesses.

Re: hardtop wiper noise, etc.
 

The fuel pump can make a pulsing noise at start up....

The one in my Cherokee uses a ballast resistor when running to lower the
noise from the pump. I don't know if the TJ drops the pump voltage or
not.
