Series III XJ6 Wipers Dead

Hi All-
Hoping one of you may have already worked thru this issue and have suggestions. Recently acquired this car from out of state, and during a post-purchase inspection was told by the local shop the wipers were "operating slowly", but now wipers do not work at all. Car runs and drives fine, all other electrics working as well. Checked fuse 6, fuse fine, put multimeter on it and found no power to fuses 5 and 6, all others fine at about 12.4V. Looked at Jaglovers and here for ideas, and was suggested to look at the Ignition Protection Relay, so found a used one online for $20 and installed. No change. Interestingly, after installing, but before trying the stalk switch, was getting a reading of 0.45V at the fuse box, but after trying the stalk switch, meter reads 0.0V. I have the Jaguar Shop Manual and a wiring diagram for this model, but unfortunately only rudimentary mechanical skills. Any ideas on next steps? Thanks and regards,

So I guess I'm really a newbie, as I'm not sure I understand what you mean by the socket for the load relay...are you speaking of what I called the ignition protection relay or some other part? I don't want to assume anything here....I went ahead a got a rebuilt wiper motor just in case that turns out to be the issue...if not, will keep it on the shelf for future use! Thanks, Doug.

As you suggested, put multimeter on brown wire this afternoon, and showed 12V....took off the IPR and tried to clean up the connections a bit. put it back on, and lo and behold,, 12V at fuse #6!...still nothing at 5, but I'm focused on 6...
But when I hit the stalk switch, still nothing...no movement, no sound, nothing.... And now when I use the meter on #6, back to almost nothing. Does this mean the stalk switch is bad?
Tks,

Weird. I don't have a snappy answer for you.
Early morning random blurtings....
My gut tells me you still have a problem with poor connections somewhere along the line. Did you clean the firewall junction posts in the engine bay? If not, do so. That's square one. Make sure to disconnect the battery first.
Just for the heck of it unplug the wiper switch entirely and see if anything changes at fuses 5 and 6
I'm pretty sure that the fuse #6 weirdness is related to having nothing at all on fuse #5...but maybe not
After cleaning the junctions posts.....
Unplug the relay again. Make a note of the terminal markings on the underside of the relay and their corresponding position in the relay socket. Run a jumper wire from the terminal 87 white/pink wires to the terminal 30/51 brown wire. Does anything change at fuses 5 and 6?
(Don't confuse the white/pink wire going to terminal 86 with the white/pink wires going to terminal 87)
Cheers
