See the attached photo. 8 pins. Knowing where they are can facilitate finding them with a tool, and can minimize breaking something.

Thank you for responding. I measured the current draw this morning and it was 5.5 amps with the overload component bypassed, and to door is locking/unlocking fine. I think I'll live with this and see how it goes. The van is used maybe once a week just by me, so the lock doesn't get a lot of cycles.

Update and a question. I bench tested the actuator and it did pull the arm in and out, but not enough to lock/unlock the door. The internal fuse/resistor was maybe 3 ohms, so I left it. Later, just for fun I tested it again bypassing the resistor, and it was much stronger. It now operates the door, ...

I just found this post referring to an internal fuse that might be bad. I've bypassed such a fuse in one of my window motors and put in an inline fuse. I'll add this to my diagnosis.

2001 Astro AWD LS My passenger door is not locking or unlocking electrically, but is fine manually. The other doors work remotely as normal. I can feel a slight kick (it's trying to move) in the manual lock/unlock knob when I try to lock and unlock the door via the remote, so it seems like the actua...

2001 AWD

When I start forward on drive pavement, which wheels are initially propelling the car forward--a single rear wheel? I have an ex Hertz rental van which I believe has a non-locking rear differential

Thanks.

Thanks. Maybe I'll start with the wheel bearings. Also, is it ever done that one starts a vehicle on a lift, tires in the air, and puts it in gear and accelerates to locate sounds?

It may have been there all along, but I'm guessing not. It's a very faint "whoop" "whoop" noise which is rpm dependent, and is--I think--coming from the middle or rear of the van. If I'm motoring along on a quiet night below highway speeds I can hear it, but it stops if I shift i...

Replacing the fuel tank pressure sensor fixed my long-standing P0446 code. It was a 10 minute fix since I have cut an access hatch in the floor of the van. The code was pointing to a restriction in the evap lines, which it may normally be, but with a bad sensor the computer couldn't even run one or ...

Excellent. Thanks for answering.

Hope I got the right section. Over time I've been looking at the potential causes for a P0446 EVAP code. I've replaced the gas cap, and bench tested the vent valve which it appears to be fine. Yesterday I pulled the fuel tank pressure sensor, but left it still wired up. The reference wire had its 5 ...

2001 AWD 112,000 miles. Only other rear diff oil change was at 30K. 1. Learned: don't refill too fast at the end or you'll have excess pouring out! 2. Question: With the cover off, there is a large opening on either side where one can peer into what looks like the axle housing on the outer side of t...

Thanks. I also found this Amsoil site that lists the fluid upgrades that have happened over time for this van, and lot of other specs.

I have a 2001 AWD van that started our as a rental van and hasn't had any mods. It runs great. The door RPO code shows GU6 for the rear axle. There are no other RPO codes beginning with 'G'. The owners manual says to use 80W-90 Axle Lube in the rear (standard?) differential, but the Factory Manual s...
