How to replace the windshield washer motor on a '99 Grand Cherokee, 4.0L engine?

It's my GF's vehicle and I don't have it here now to look at, so I'd like to know what I'm getting into, like:

%26gt; if it's the kind where the motor is on the bottom of the reservoir, is it an easy replace?

%26gt; would I be better off just replacing the whole assembly?

%26gt; is replacing the whole assembly easier than replacing just the motor?

%26gt; if I replace the whole unit, does it have to be brand-new, or am I likely to find a good one in a junkyard?



Hoping for some good advice or good links. I've been looking online for a few hours already, so if you just start Googling now you won't find anything I haven't already seen; thanks, but no thanks on the wiki link, I already checked that one out.How to replace the windshield washer motor on a '99 Grand Cherokee, 4.0L engine?
The washer motor should be at the bottom of the reservoir, or sitting somewhere beside the reservoir, close to the bottom of the tank. It is a lot easier to replace the entire washer, only a couple of bolts holding it in, plus the clamps for the intake and output washer hoses. Less than a 30 minute job, and the washer motor should be less than $30.
