Intermittent Electrical Fault (problem Solved)
My 90 525i has developed a electrical fault in that the Central locking, electric windows, radio and interior light all fail after about 100 mts driving approx 15 minutes later all start working again meaning I cannot lock my car or wind the windows up, I can turn the interior light on by way of overhead switch but will not work off door switches, I replaced the battery approx 2 months ago, I fitted an alarm, stereo about 1 year ago I disconected the alarm thinking this may be the problem but it was not, I have spoken to various BMW experts who cannot diagnos the problem for me, I suspect it is either a worn relay or thermal overload switch neither of wich I would know how to find. any help would be GREATLY appreciated.
