Need Help Water Leaking into Cab

[rangerbert]

I have a problem with water leaking into the cab. It's coming in from the top of the rear window or somewhere close havent pinpointed it yet. I've read on here before or maybe another site that the 3rd brakes light was the problem. I don't remember what to do to fix the problem. Can anyone give me detailed information about this. If So Thanks in advance.

read here .. . . . . clicky! will explain how to fix the leak if it is from the third brake light. I have done the same thing myself and haven't had any further problems for well over 6 months now.
