Strange electrical issue

[grinder143]

Well there seems to be a gremlin or something. Per seat works most of the time but not all.pwr front windows no longer work at the same time the pwr mirrors quit. In addition the cruise has stopped and the bas light came on after the breaks were replaced . Any idea on how to start to troubleshoot some of these items.

bas is the bas unit under bonnet under brake servo a little black box three connectors on it

the set and windows could be the sam unit but best and cheap thing to do
is get the error codes read on a STAR MACHINE

and you will know asap
