Wipers no longer park..

I have an annoying problem on my '94 Jeep Grand Cherokee Laredo.. the
windshield wipers no longer self park, and the 'intermittent' does not
adjust.. get a sweep maybe every 15-20 secs only.. there are no obvious
relays that control either feature.. what should I be looking to check to
fix either/both problems?

TIA

 

A lot of newer wiper systems have all the controls attached to the wiper motor.
I had a similar problem in my 1998 Saturn and once diagnosed as a relay problem
I found that the relay was attached to the actual motor. I removed the motor
and replaced with a new one and was curious as to what all was in the motor
housing. I opened it up to find all the relays in there. The one that controls
the intermittent was pitted and fried.

 

Thanks for the info.. I had a feeling that it wouldn't be a 5c 5 minute
job.. oh well..

 

My Caravan, (might be the same) has just a manual park switch inside the
motor unit. It is pushed open as the motor passes its park position. The
switch is used for more than just park. It is bypassed when the wiper should
not park, and it is used to signal the intermittent stop position. It is
quite common for the switch to corrode, or just get so dirty that it can not
pass the park position information signal. On more than one occasion when
mine did this, I was able to remove the unit, open it up and clean the
switch and restore normal operation. However, once the problem occurred, it
re-occurred every year or so again. On my Caravan, the access and removal is
lengthily, so on the third time, I broke down an installed a new motor.
Problem now gone (several years).

 

I would sooner replace the motor.. at least that way I will get reliabily
for a longer period.. what am I saying?.. the way that parts are made today,
who the hell knows.. ty for the info tho..
