Have a rather strange problem on my '94, driver side windows will go down ok, but on raising either front or rear, after about 2/3 of the way up they will stop and not function for a few minutes, then will go up all the way most of the time, at the time this happens the passenger side functions ok, so believe the circuit breaker is functioning ok, before trying to tear everything apart thought I would check with the experienced folks here. Any ideas?
