BrianH Posted February 20, 2015 Report Posted February 20, 2015 (edited) Hey everyone Has anyone else had the wipers fail to stop when switched off (they run on either full speed or slow speed, but switching them to intermittent or off keeps them on the slow speed). Its a mk1 aspen 2.0 petrol 97 reg but appears to really be a later 98 spec somehow(no lock module under seat, 3 layers to fusebox etc). Wipers have played up previously failing to do the intermittent and slow speed but seemed to just fix itself. Guessing its a new stalk or relay just not sure which relay controls them (actually found it may be relay 53) or if there is a common fault besides them being seized that might cause this. All the broken wires in the gaiters repaired late last summer so think they are ok. Cheers Edited February 20, 2015 by BrianH Quote
seatkid Posted February 21, 2015 Report Posted February 21, 2015 (edited) This is a usually due to a common fault, water ingress and corrosion on the control pcb. This module is located on the motor itself. Tech FAQ 60 Removing the module and drying it out can often restore it, if not..... A replacement module is horrendously expensive, probably unobtainable. The two possoble solutions is to source a unit from a scrappers, or be brave and strip the module down. There are pictures somewhere on the forum showing this. The small pcb is conformally coated (fancy lacquer), but often not to the edge of the board.Water gets into the module when it rains, and eventually the moisture gets under the coating causing the copper tracks to corrode and fail - its obvious where the damage is when to examine the board. Using a combination of solvent (try brake cleaner), a stiff tootbrush, a bit of poking and cutting/bridging out the corroded tracks (soldering iron etc required) you may be able to repair it. It has been done a couple of times by some of our members Hope this info helps. Edited February 21, 2015 by seatkid Quote
BrianH Posted February 21, 2015 Author Report Posted February 21, 2015 Its given me somewhere to look. It does explain the original issue somewhat. I noticed the bottom of the motor cover was all loose before but didn't realise there was more than the motor there. Will investigate and maybe get the soldering iron out. Cheers will give it a go and see how that looks Quote
