Problem number 3 of my car is you guessed it, the power antenna pops right off, the mast is bent slightly and the brass lock that snugs it seems a bit bent of one of its lucks. It pops off no matter if the Screw type lock is open or closed. It got to the point where I just removed it and I dont have a mast right now. The motor whirs and seems to function. Question is though, is it just the mast? Or could the assemble itself just stop holding the antena in place?

Man seems that my decided to have 3 problems at once. Parking Brake light stays on when I disengage the parking brake, Yesterday I noticed a small oil leak, (I changed to synthetic 2+ weeks ago) And now the mast pops off till point of where I just removed it!
