E91 random window opening

Post by Tbmw » 24 May 2018, 16:12

Hi people my E91 has developed a very annoying fault that when when driving the passenger window will just randomly open sometimes all the way, sometimes part way. its not all happening every time i drive but when it does it happens for the whole drive, its very frustrating to keep fighting the window to keep it closed.

any suggestions?

Thanks in advance

Sounds like sticky buttons, give them a squirt of contact cleaner.

If it only goes down (uncontrolled) suggests one of the wires is chafed and earthing. Have a look at the rubbery tube between the door and the A pillar and look for damage.

As above, prise out the switch and check for corrosion.
