I have a 2005 SiR 2 door hatchback. LHD in Canada. I understand that this is a model that shipped only to Canada and parts of Europe (correct me if I'm wrong). Therein lies the problem.

My LH window regulator failed and I'm having a lot of trouble sourcing the correct replacement. The only coupe specific regulator I could find has a 4 pin harness whereas my original regulator has 6 pins. I thought I'd be creative and tried to splice the 6 pin harness to the new regulator on the assumption that the extra two wires were power and ground. I tested it and I'm pretty sure I fried my window switch. So I'm back to square one.

First question is - what's with the 6 pins? What do the extra two wires do? Why would a non-SiR coupe have 4 pins and the SiR have 6?

Secondly, has anyone tried separating the mechanical regulator from the motor? If I could just replace the mechanical parts, then I could just use the old motor and harness.

I'm probably going to have a tonne of follow-up questions so I hope you folks are patient.

Thanks.

 

Call your local dealer. Give them your VIN number and ask the parts department to give you the correct part number for your car.

 

interesting ... I have the exact same problem. I joined this Forum in effort to find data on the power window system in the 7th Gen SI. I wish I could contribute to the solution. The only info I could provide is the Honda OEM part number for the window regulator / motor assy. It is 72250-S5S-G11. I found it for sale online for $225 plus tax and shipping. All the non-honda ones (e.g. Doorman) do not have the 6 wire plug. And the wiring diagram I have only shows 4 wires, yet the actual unit I removed from the car has 6 wires, like yours (see attached photo). Also, mine the mechanical cable broke. so all I really need to do is replace the cable ... but the where the cable goes into the gearbox is not accessible.

I called my local dealer, asked for the Parts department, then got re-directed to a call center (sounded like India) where they wanted a ton of personal information. After 5 minutes difficult to understand English, I gave up.
