Hi

I have read a lot on here about fixing issues and its been so helpful. For some reason esp. BreezyPete's advice. have been systematically replacing parts on an honest but tired Fab bought for my kids and its going well.

BUT

I dont have remote fitted just key. replaced door locks due to microswitches. Left front now works perfectly, flashes indicators, courtesy light, window trick works both ways. Right front intermittently opens/locks all but often just itself, no indicator flash, no courtesy light, window trick doesn't work. I check door loom at a pillar and AFAIK there are 2 wires with broken insulation but still connected But otherwise OK, when I reconnected there was some CL activity as connection made.

Do you think there must be loom damage inside the door, or CCU, or what else?

Thanks very much.

 

As an aside. Its the 1.2 HTP at 109k. Should I do timing chain as precaution or is it reliable?

Oh sorry. I just found breezy petes guide to checking door loom so I will do that first!

I would suspect the window motor module/its connections local to itself, even if the window is working fine from the switch. 

 

The 'key turned in lock' signal goes via the window motor, and isn't simply passed through it.

You may be able to see traces of green corrosion residue on the right-angled adaptor bit that takes the loom connector wiring down onto the circuit board if you carefully unclip it from the top of the motor There are long fork-like prongs that connect to a board-mounted male connector, and these seem to suffer from condensation mediated corrosion, both of the contacts and under the black plastic body. 

 

Unlike some posters on here, I tend to believe that a careful visual inspection of the door loop wiring is generally all that's required, broken wires are usually very obvious.

 

Replacing the timing chain on one of these engines is more likely to cause problems than prevent them, in my opinion.

It's a big, tedious job with lots of opportunity to knob up.

Keep the oil fresh/young and never park it on a slope in a gear which would tend to make the engine rotate backwards if the handbrake allowed a little movement.

Thanks. Checked motor inside and its like new. I cant see anything obvious anywhere so I will do some end to end testing.

on the plus side I fixed a window issue by removing and cleaning the outer trim seal. OMG absolutely caked in gunk, window must have been virtually sticking to it.

I will leave chain alone. Just done belt on my diesel and that was so much effort but gotta be spot on with interference engines! Albeit keeping oil regular and fresh is not one of my strengths, but thats a whole other story involving a pos mini!
