How do you get to the back spark plugs on a 2000 Chrysler Town and Country to change them?

It is quite easy. 1st remove the windshield wipers. then remove 4 or 5 torx screws that hold the plastic cover on in front of the windshield. once that part is removed, there are about 4 bolts and 4 nuts that hold the windshild wiper tray and mechanism in place. Remove them and disconnect the power/contrl plug and lift off the assembly. The plugs and back of the engine will be accessable.

I just did my 99 T&C. Had to remove the wiper motor arm cover assembly just below the windshield, the air intake box, and unbolt and slide aside the air intake manifold-NOT a fun job, so I put in the most expensive plugs-hoping to not do this again for another 50-75,000 miles !!!
