Help with diagnosing cab top

[wlee69]

My '01 cab has been make the "clicking" sound from the control module for the last year or so when the car is off and the key is out. The cab top operates perfectly - its just weird when I take the key out and the car is shut off, the control module goes crazy with the clicking noise! Its was off and on for awhile, but now everytime it happens and is making noise right now in my garage!

Here's my logic so far.....I'm assuming if the open/close cycle works, then there is no issue with any of the microswitches. So I knew my ignition switch has been turning weird (mushy key turn) so I thought maybe that was making the control module click all the time. Replaced the ignition switch last weekend..still get the clicking noise.

Checked the durametric codes tonite and I have the 01 fault code - implausible switch position error. The only other thing is that maybe the control module in the rear that making the clicking noise has a faulty relay or something in it? or can a microswitch be faulty but the open/close cycle still works fine?

Saw some used control modules on ebay @ $250 - but wanted to check to make sure my logic on pinpointing things is correct.

Thanks in advance,Will
