Question about Acura MDX
they all guess, do you want me to guess, too? surely not.
or test?. we can use a voltmeter to find this.
what we do is look at the schematics at alldata.com
and its all clear. a simple road map;
Sticking on possibles.
the fuses are underhood. fuse 11 and 31
bad motor , internal keep alive cam switch stuck on,
will cause continuous wiper.s
so will motor colored wires green or blue hot full time
will keep motor going full time (any voltmeter, easy check)
12vdc is bad, 0v good (wipers off)
next and last is that wiper relay in hood fuse box, shorted. (pull it out see if they shut off?)
if the relay is good then its input is wrong. the control block.
the combo switch wipers on , sends a CAN buss digital commands to the MICU control block, this i turn powers up the wiper relay.
the MICU has a diagnostic port,and can be tested at the dealer
if the relay coil pins are hot all the time, then the MICU /combo side is failing, if not, the problem is the relay ,if its output is hot all the time.
how is that?

Well sure enough all I had to do was replace the circuit board...wish I had done this a couple months ago...it was so easy to do and will now be much easier to drive with being able to see clearly again....

This solution applies specifically to a 91 Ranger with delay wipers, but may apply to other years as well:
There is a "cold solder" joint on the wiper control module that should be investigated whenever intermittent wiper issues crop up. I dont have the ability to post a schematic, but it is one of the leads that come off of the main terminal, and is fairly large. The solder around the lead will look dull and will most likely show physical separation from the circuit board itself. Re-solder with a good hot iron and it may well cure what ails ya. Takes 30-45 minutes, depending on how adept you are at worming your way under the dash to retrieve the module. It's to the left of the ashtray about 6 inches.
