help! wiper/aircon elect issue

[jamaz]

I have a problem with my vt , when i switch on or off the air con or demister switches the wipers come on, could the wiring be crossed??

yeah mate thats not right, does it do it every time you press that button, and does your windscreen wipers come on only when pressing that button?

and have you re-wired it recently?

My guess is that it something to do with the BCM.

Just bought it havent touched the wiring. the wipers work fine otherwise, but when i click demister or aircon on the wipers cycle one time. i removed the wiper relay and the wipers still worked except for park function but the a/c switch problem was gone - im suspecting a possible relay problem
