This is not my car but a good friend of mine l322 4.4v8

First fault present when car was purchased the rear window lock switch is on all the time, it stopes the rest of the controls working on the drivers door assumed it just needed a new switch pack

Also when purchased air suspension faults were presant, put 2 new rear ride height sensors on car went up and pipes both front bags, 2 new bags later air flys up no problem, even tested it in off road mode very happy, but try dropping it down the rears go straight down no issues, the front however rises or stay the same if fully up, I traced everything back to the valve block took it off and tested all the solonoids which all worked fine (I think)

Put the valve block back on still the same, tested the middle solenoid wiring and I get no 12v signal at all, both end solonoids get 12v when lowering and raising but the middle no matter what you do have has no feed (when using the original connector, will try it now to another earth just in case

Any One any ideas? Sadly the car is not known to me purchased with issues at the right price

Could the 2 be related or am I just looking at 2 seperste issues at the same time?

So out of interest I removed the faulty switch pack (it has been left connected so all the door lock from remote)

As soon as I removed the faulty switch pack I got a feed down to middle solonoid think I had read 12v at one point but then 2v regularly, this could be because I don't have 8 hands, holding phone operating air suspension and one hand trying to hold the 2 probes in the connector

RE window switch pack - if someone leaves the window open when it rains they can get damaged.

I would swap the whole unit out - they are cheap on ebay  

Sorry for the late reply, the faults are not related

The window switch pack needs replacing, opening up the old one I can't figure out why it would fail given it is coated in plastic?
