I have a 2002 Town & Country Van 3.8 the power liftgate dose not work, It will make a beeping noise and act like it wants to but the latch dose not seem to unlock all the way. Have to use key in it and turn and hold to open. What part should I start with the power actuator or? Thanks, James

Sounds like the internal latch assembly is not working properly.

go there it should help

spray the latch down with starting fluid to remove grease then spray it with silicone to lubricate as grease will bid up lock lever worked for me

Does it power open at all. If not I bet its the latch. This is pretty common on these. Also I have seen when rust will build up on the hatch lift supports. The door will pop when it opens Just clean off the rust with some sand paper.

it is one or two things camshaft or crankshaft sensors

try to test the battery and put a load on it. with a low battery sometimes the computer acts up.

Replace the latch mechanism. There is a short in the latch. It happened on both of my vans. The latch costs about 90-100 dollars, if memory serves... 3 bolts, a wire connection, and the manual latch bar. Very easy, shouldn't take more than 5 minutes to switch out.

check inhibit switchs with scan tool,codes etc....possible faulty PLG latch,,(power liftgate latch)

Replace the lock on the rear door. If a used lock is used it has to have the powered door. I am a car dealer and have replaced about 8-9 of them. I sell a lot of Town & Country vans. The 1st one I paid a Chrysler dealer to fix. About $200. After that I fix myself. About $70- $125 from a Chrysler dealer new with discount. The lock is not sending the correct code to the computer and the door is confused on what to do. Only 3 torx bolts to remove and the door panel 2 screws in handle then snap off.
On one I had that did not fix the problem and it was a relay sensor about $40. on the working arm / motor of the door and not the lock. Look at car-part.com for used parts. Thanks, Roy

try this out. this might help. I am still looking for a solution as well. the shims mentioned here dont seem to work for me. the latch will not disengage and everything stops. http://chryslerforum.com/forum/showthread.php?t=4534&highlight=2001+liftgate
