1 I have power to switch
2 I have power to the main relay in boot
3 I have no power at last connection to pump
4 I have connected pump straight to 12v and it works.
5 fluid level in pump is ok
6 checked continuity of switch which gives a reading so that does seem faulty( no expert though just watched vid on you tube)
would I be right in thinking it's the switch or could it still be something else. When I try the roof there is no noise or no clicking it is just dead.
is there a way of testing switch as don't have replacement it has a 5 pin connection can I connect 2 of them wires together or something like that to see if it works?
glad of any advice and if anyone can recommend where to get a switch would be good…
many thanks

you should see 12v on the grey wire with the ignition off, this comes from the ignition switch pin P (parking lights) permanent live to the red wire which comes in via the fuse, and you should have a brown earth wire which goes to the boot somewhere.
theres a purple wire which goes to the 2 hood cover contact switches, they disable the motor if you have the hood cover fitted (close to ground) so check those out in case one has failed closed

On the switch I have 5 wires red/brown/blue/green/ and a grey one with blue in it.
Is there a way to test the relays?
The key in ignition is a bit dodgy as well you have to wiggle it and hold it down to get any volts. Can this be bypassed?
Sorry for all questions and thanks in advance

if its red it may just be a slight deviation in the loom when built, you do see this sometimes or its been replaced at some point, but regardless 3v is too low you should see 12v so if you can find another 12v feed push it into the back of the switch pin temp to see if that helps.
grey/blue is switch illumination, brown is earth for switch illumination. then the brown/red is the power input, grey and blue are power outputs to the roof relays. if you jump a wire between the brown/red and the grey and blue wires see if the roof moves, if it does this tells you if the switch is to blame, if not then its the power feed to the switch, something at the relay end or possibly the blue or grey wires are damaged somewhere
if the key-in-ignition is bad you can tap it to another feed, it'll have to be either permanent live or to the P wire from ignition switch unless you also tap a feed to the P pin as obv ignition live wont work since P goes dead as soon as ignition is switched on.
any yes, in general jumping a red wire to brown is a Very Bad thing to do so you were right to query
