there is what appears to be a 90* vacuum or some other fitting in the backside of the drivers side front fender.  My windshield washer doesn't work maybe this is why, but my 4x4 doesn't engage either, maybe this is why.  

 

Thank you!!

The vacuum and washer are seperate. Just had cowl off and disconnected the washer under the cowl on the left side. I did not pay any attention to where the line ran. But it would not surprise if it was on the left headed towards the resevoir along the fender.

 

The vacuum could be leaking any where. If it is all original I would start at the pump and follow it and replace any bad fittings along the way. Does you ac/heat blow out of the dash vents?

yeah, the vacuum seems to be working fine for HVAC, but near the firewall one of the connections is capped (hmmm.. why would dodge put that there to just cap it I ask myself)  :-)

Cruise control is one. My 02 is fly by wire and most likely your 01. Late model manual trans came with fly by wire. Mine has a couple capped off IIRC.
