w140 trouble with climate control (blower)
93 400sel, during longer trips with AC on automatic the blower stops working. It sounds like all is still working from behind the dash but no air coming from vents. It appears to be still cold at the vent so looks like evaporator working etc.. I can reset by pulling the fuse and things start to work again. Short trips don't seem to be an issue and once car has been off, on start-up back to normal??? Any ideas for a potential DIY fix?
