Frozen Sunroof Cable

[73ess]

Just found the cause of a non moving sunroof in my 911. After removing the sunroof panel, all the aluminum rails and dropped the gear drive. I tried pulling on the passenger side sunroof cable and it slides in and out of the routing tube just fine. But then I tried pulling on the driver side cable and it's frozen tight. Was thinking of shooting some PB Blaster down the tube entrance that the cable inserts into, but the diameter of the cable is just a tad smaller than the diameter of the tube opening. So unfortunately can't get the PB blaster far down the tube. But sprayed the tube opening as best I could. I was thinking of maybe using a heat gun to heat up the cable with a heat gun. Perhaps the heat would conduct along the length of the cable, thus expanding the diameter of the cable just enough to break it free? That's assuming it's rusted somewhere to the inner wall of the tube it's routed through. Any other ideas on how to tackle this one?

Do you think the cable is bound in the aluminum side track. If so you should remove the side track with the cable and work the problem on the bench.

Confirmed tonight that the cable is bound to the steel tube that runs adjacent to the motor. Shot some PB Blaster down the opening at the end of the tube. Hopefully it'll do the trick!

I have the proper NOS cables with correct diameter if you don't want to fight the battle with currently offered cables. Not cheap unless you consider that the current ones don't work well.
