While not easy, by following everyone's advice on this forum I removed the old one and installed the new.

Five years ago, I replaced the rear passenger regulator in my 2000 Cab 4.

I replaced my rear regulator, you don't have to remove any convertible top components.

There is a wiring conduit just inside the cabin running along the sill, but, it did not look like this wire originated from that part of the wiring harness.
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

My 1999 C2 Cab passenger rear quarter window won't go up. I tried swapping the switches for the easy fix. I understand that there are no relays for the power windows, and the fact that all other windows and even the top goes up and down without an issue leads me to believe it wouldn't be the switches or relays. And there's no noise at all on that window, so I'm guessing the window isn't off track and he regulator is fine.
I guess I'll have to tear into it to see if I'm getting power to the motor and if there's a micro switch in there somewhere. If there was a relay, I'd check that first, but again, I don't think there is one. And I cannot imagine a fuse that individual to that window.
Even with the inside panel removed, there is virtually zero access to the regular or motor or window. It appears as though I will have to remove the components for the convertible top?
I'm following these articles that pertain:

IIRC there's a switch in there someplace that prevents the rear windows from operating when the top is down. Any chance this switch is toast (or stuck closed)?
That switch is located at the top of the windscreen near the latch and is a global micro switch for the rear windows. Since the top still operates and the other rear windows operates, I assumed it's working fine
I replaced my rear regulator, you don't have to remove any convertible top components. You loosen them, and flex them a bit to create the room to get the regulator out. I googled it, and found instructions. (Pelican parts had some instructions on it I think?) A fairly easy job. It took me about 2 hours total to remove and replace. And a new Regulator is EXPENSIVE!!! The only part that was tricky was removing the bottom regulator bolt. You have to remove the back seat bottom, and use an extension to get to the bolt through to hole the wiring runs through...
Well, I call around a few places, and the labor plus the part is looking to be VERY expensive. Basically, the cost is ranging from $1,000 - $2,000 ($800 - $1000 for the part, and then another $500+$500 for labor of diagnosis, removal + re-installation).
thechileman - did you have your regulator rebuilt, or did you buck up and buy a new part? The newest part number I can find is: 99654301606
Seems silly to spend so much on a new part, especially if it's just 2 hours, but shops around here are not giving me a quote range with accuracy, so if the labor really is more like 3-6 hours, then I can understand why a new part should go in there (places here warranty the parts and labor, so they don't want to have to get back in there again).
Thank you sir. I plan to try your method. One question, though: do I really need to put my top in service mode? My thinking is that if I fail to do the job and then cannot get the top open or closed for some reason, then I'll have to flatbed the car (in good weather) to a shop. Which is different than just leaving the top fully closed and having trouble.
I did the work with the top half way up. As far as I could tell, there is no way for the window regulator to mess up the function of the top. Also, the cheapest place I found to buy the regulator was Gaudin Porsche in Las Vegas.... They have a website.

Are you sure you aren't releasing the top closure button to soon? The rear windows go up after the top is fully closed, not during top closing, if you release button to soon they don't move.
If you pull the inner weatherstrip off you'll be able to reach the window. then try to lift it slightly from the rear. If it moves more than 1/2 inch the regulator is probably toast. They mostly suffer from the cable pulley breaking than the motor going bad.
Argh! I just received delivery of my rebuilt regulator, and they said they tested and rebuilt all components except the electronics. Well, the regulator STILL doesn't work, and the only thing left seems like the electronics. I called maybe half a dozen or a dozen places and nobody has just the electronics part laying around. Even most of the parts cars are coupes...
Anyone have any thoughts on how to proceed? I'm still waiting for a call back from Power Window Regulator, since they verbally told me that they will "make it right" if it's indeed the electronics.
I have a pair of rebuilt rear window regulators that came out of my 2000 C2 cab I'd sell. I know for a fact the electronics worked on them as they tried to make my windows go up and down. Problem was cable/pulley related.
I'll never forget that DIY job. I changed them out overnight in my garage while there was a hurricane warning a few years ago. 50-60mph winds going on outside and I was in the garage in the middle of the night, drinking Stellas, sweating like a madman, and working on a convertible! LOL!
I was hoping to sell them as a pair for $700 and haven't gotten around to it.
Ping me via PM with a fair offer for one or both if you're interested.
Thanks. Yeah, this job isn't the most fun DIY. Kind of a pain. But it turns out that the Power Window Regulator company I used has a really good tech that also owns a 996 (coupe, smart man) and does quite a few of these Porsche
per week.
He walked me through the wiring and tests and is sending me a motor/electronics assembly for cheap because of this issue. He said that he's only seen 1 electronics piece fail in as long as he's done these. If it's not the electronics, then I'll have to test the wiring harness (I pray that isn't the issue).
Wow, working on your car through a hurricane is a hard core enthusiast trait I admire and respect good sir.
Five years ago, I replaced the rear passenger regulator in my 2000 Cab 4. While not easy, by following everyone's advice on this forum I removed the old one and installed the new. The same regulator went bad this summer.
Last Monday I took the current regulator out - no problem. Saturday, when I went to install the new regulator, I could not find the wire with the 6 pin connector. I looked where it should be, I looked up the tunnel through the rocker panel. To see straight down the tunnel, I removed the drain behind the rear wheel liner. I used a snake with a light on the end of it to look up the tunnel. Could not find it. There is a wiring conduit just inside the cabin running along the sill, but, it did not look like this wire originated from that part of the wiring harness.
Questions: Where might the wire have gone or should be?, If it is up the tunnel, how might I get it out? Are there any diagrams that show how this part of the wiring harness is laid out? Any suggestions?
Many thanks,
Jim
Is it easy to disconnect the power wire to the window regulator? I think I see the power wire in your picture. All I want to do is disconnect the power to the right rear window regulator by taking apart as little as necessary. I am able to manually lift and lower the window by pulling and pushing it by hand and I am OK with that. If the power wire stays connected, the regulator runs on and off if I have the top down. I know I am about 3 to 4 years late to this post, but maybe you will find this reply.
hi, what parts did you need to replace in the regulator?
do you still have the email from eBay or picture of the eBay repair kit you could share please?
Kit is available on Amazon also.
