Every time I've replaced a stalk it was for cosmetic reasons: the chrome-like coating peels off and the lettering disappears. It's possible that the cruise and washers are failing at the stalk, but I would bet against it. Did they both fail simultaneously?
From recollection, it seems that the washer is actuated by pushing on the paddle, but the actual switch is not part of the stalk that pulls out. I believe that switch is still inside the steering column.
I have also replaced a number of windshield washer pumps. They don't last forever. If the pump is gone, you will get the wipers to cycle, but no solution is pumped out. If you have the intermittant wiper option and they don't work, then it may be the cover of the wiper motor. There are some electronics in there that can go out. I found a junkyard cover that solved that problem for my T.
I've had 3 TR's, all with cruise contol. I've never had one problem with cruise...just lucky, I guess.
