- clk 430 avantguarde convertable w208 2000 plate
hi all, new member be gentle with me
i have owned my clk convertable 430 avantguarde for about 5yrs now and rarely use it these days and recently decided to give it some TLC. new suspension coil springs dampers, refub front wheels and brakes..with the recent sunny weather its been too good to not have the top down, and heres the problem..its never ever let me down until now..
the problem being as follow.
after releasing the hood from the front screen and pushing it up slightly, when using the center console switch to activate the hood, the front & rear windows drop as expected, but theres no movement from the rear rollover headrests. and are now in the down position & work using dash switch( dont ever think they did in-fact move when openong the hood ) )the switch then flashes continuously whilst pressed or pulled and thats as far as the hood mechanism goes..
so far i have uncovered the hydraulic pump and control unit ( thanks to youtube vidoes..absolute boon that site ) all looks good, no leaks resevoir correct level etc.all catches locks and cables in good condition and working well, have given all a good dose of WD40.
i have checked all fuses and the relay changed out for a known working unit.
still no movement from the roof.
so basically im asking for any suggestions before i go down the route of swapping the control unit and or pump unit ( expensive even second hand )
would getting the ecu read tell me which component has failed ? i have an OBD11 scanner but its not reading any faults, does it have to be STAR as i have been reading other posts and as i have one or two unrelated faults now showing on the dash maybe this is what i need,,( again very expensive bit of kit, too much to warrant me buying my own )
the micro switch in the boot works as well, so i know thats not the problem, so im now stumped...are there any methods of testing the pump unit without spending thousands on a testing kit.
over to you guys and girls..any suggestions greatly appreciated.
p.s. my blower motor runs non stop and ive had to take the relevant fuse out to stop it, any one able to tell me where the relays are hiding so i can swap it out...no mention in any of the handbooks that are original and came with the vehicle.
thanks everyone for reading and hopefully coming up with some whizzard way to fix my roof !!
