Validating my guess that the stuck passenger window is due to heat, a late night drive to pick up some munchies found the passenger side window working again. I do need to get the motor replaced but I’ll do it in the spring together with a bunch of other stuff.
Been thinking about putting a satelite radio system in the MINI but some research has shown that it’s impossible in a 2002 MINI as it has no aux input. My only option is to replace it with a non MINI radio which seems like it would spoil the look. Something to look into though.
