what are the wires for on the rear hatch door hydraulic pumps
Electrical... try plug wires
I was quoted $120 without new spark plug wires.
When was the last time the ign. wires were changed?
you can reach them by removing the tires and the wheel well guards [plastic]
Plug wires are installed incorrectly.
you can get to some from the front and the ones in the back you can get to through the wheel wells
It can be eithier plug wires crossed or burned valves. Have it checked out.
The crank position sensor On your astro is located on front of the engine on timing cover, left side. Behind the crankshaft pulley. with a connector of 3 wires.
It is located behind the coolant and windshield washer reservoirs. The two wires on the blower motor will lead you to it.
Under the dash by the stearing column is a fuse panel. Open it and look for two stacked curcuit brakers. They look like silver boxes. Pull out the lower one. It controls the rear hatch. Push the rear hatch release button several times and reinsert the curcuit braker. It will pop the hatch open. Open the rear door and open the little access panel. It's located on the side of the door, and it has four screws. Look inside next to the latch and lock, and see if the wires are loose. The wires and prong should be touching/attached. Mine weren't. Whatever held the wires to the lock shaft fell off. My husband temporarily fixed the problem by attaching the wires to the lock shaft, slipping an ihook over the pin, and crimping the ihook with vice grips to secure it tightly. After replacing the access panel, he checked the latch release button and key several times, and the rear doors opened. He plans on checking another Astro Van at our local Pick A Part Salvage Yard, to see what should be attached to the wires, but for now, this works.
It is located at the end of the top radiator hose (engine side) It is in a housing with 2 bolts probably has 1 bolt and 1 stud with wires attached to stud
