Leak at 'A' Pillar grab handles
If it is on the a-post then it is most likely the door seals. There were problems with those & there is a TSB for it. It also fixes the problem where the door rubbing the seal eventually tears it. When you get it done make sure to check the two screws in the inner seal up near the top of the windshield. If they don't get those tight ( like they did mine) it will still leak with the new seal. I tightened those up on my 04. 5 & didn't have any more trouble. I currently have an 07 with factory cab lights that have been leaking. Those seem to leak around the sun visor posts & drip on your leg/seat. If it has been going on for very long you might want to check the headliner for water damage/mold etc.
As an update and the final fix on the water leak problem, I ended up taking my truck back to the dealer after the wife's leg got soaked by the water dripping from the two trim plugs over the screws in the handle on the 'A' pillar. Man, was she mad! There was a cold rain that night here in VA when the leak was discovered, and I'm sure it startled her!
Before my appointment at the dealer, I did read the threads here in the TDR and also went to check any TSB's that might address the water leak problem. I found TSB 23-003-04 on the following website:

I noticed that two of the clearance lights on the cab had moisture in them. That told me that somehow, water was leaking into them, or coming up into them in some way. Because of that, it may be possible that water could leak into the cab. I decided to get in touch with the dealer and get some new lights.
My dealer did not have any cab clearance lights in stock, so I called a different dealer close to me, and found out from their parts department that there was an update on the clearance lights on the truck, and if you replaced one, that you must replace
all of them with a newly designed light, Dodge part number
5507559AD. They had several sets of them in stock, along with the nylon nuts that press fit into the top of the cab which the screws in the lights thread into. {These "nuts" cost more than the lights, by the time you get 10 of them (2 per light)}. I got the light assemblies for $6. 10 each and the nuts for 3. 50 each and went home to replace them. I printed out the page of instructions from my service manual CD and proceeded to remove the old lights.
The first thing I noticed about the new lights versus the old ones was that the gasket under the lights was different. The new gasket had a "lip" that fit over the light at the bottom... that is the light would fit down into the gasket and possibly seal better against the light. I could not tell if there had been water leaking under the gaskets which would have shown up as a "water line" or "dirt trace" on the cab around the holes. So, I cleaned the top of the cab where the gasket mounts, then replaced the nylon nuts in the holes in the roof. I then "fitted" the light down into the gasket, insuring that the lip of the rubber gasket was even all the way around the lower corner of the light, inserted the light socket into the light, and mounted the assembly to the roof and torqued it down to 15 in. lbs. of torque.
The following week I took the truck to the dealer for the appointment, and discussed my problems and what I had done with the service writer. I also presented them with the copy of the TSB about the cab water leak I had printed from the website. They were amazingly attentive, and told me that they had scheduled a company that works at their shop to diagnose and repair vehicle water leaks to work with my problem.
Two days later, they called and told me that the company had diagnosed and repaired the problem, and the leak stemmed from the problem listed in the TSB. Although I might have had a leak at the clearance lights prior to my replacing them, there were no leaks at the cab lights at this point (which was good).
Following this posting, I will try to upload some pictures of the old lights with the condensation in them, and of the new lights so you can see the difference in the gaskets.
At this point, the leak is fixed. I hope it doesn't return, as I don't want to be disappointed that this truck has lights I really didn't want in the first place.
