I have a 87 735i with some electrical problems.:
1 - Heaters seem to have a mind of their own - turning itself on and off as it likes and unable to switch off.
2 - Cruise control sometimes stops working during driving (not during use, but after braking and trying to turn it back on again)
3 - Dash lights sometimes fade in and out (not fully)
Could this be a computer problem???
Any help much appreciated
