I have a 2000 Chrysler town and country and every

Sounds like you may have a bad vacuum brake booster leaking vacuum or your torque convertor is not unlocking for some reason., there are many things that could cause this though and without thoroughly checking it out this is my guess. Hope it helps

You installed parts & asked for various services to be done

What you failed to do, was testing required to find your vehicle
problems

Most likely, unless your way behind or never do any Preventative
Maintenance, you didn't need all that was done,at least to fix the
cutting off issue

Have to check for OBD Codes,road test with scan tool,look
at data & component test, to find problems,not replace parts
in a wish & hope strategy

check the spark, sounds like the coils are going bad but it may be a fuel delivery problem.

You did not say whether the inside or outside, so here is the instructions to both.


And here is for the outside door handle

best guess is that you lost ground to the cluster, start at the battery and dissassemble the grounds and clean them, nest step is to locate the grounds under the dash, good luck

you need to put a scanner on it and see what code comes up.
my guess would be the crank sensor which is very common .

You need to replace the window regulator and the motor as well if it isnt functioning. Once you remove the door panel it is pretty accessable and not a hard fix if you have basic automotive experience.

On the center overhead panel directly behind the overhead compass display are two switches. Push them outward to opem, inward to close.

Possibly the camshaft and crankcase sensors. I had similar problems with my 2001 Town and Country.

This is not uncommon, chrysler spec say that it may take up to 5 seconds to engage when cold. Make sure your flid is topped up to the proper level and I recommend a trans tune every 50,000 kms. Also, your dealer can do a quick learn, which resets all the factory values(recommended after every trans related repair).
