I recently purchased a 1989 740 GLE Wagon. We've had some recent heavy rains which as lead to the discovery of some leaks. I repaired a leak on the driver's side by resealing the fresh air intake panel cover. I had a second leak on the front passenger side. Water was coming in through the blower motor. I removed the cowel and resealed the snorkel piece that sits over the blower motor. I also resealed the splash guard that sits over the entire area. The blower motor seems to run better already (it was making a groaning noise prior to repairing the leak). HOWEVER, now, whenever I turn on the defroster (the blower motor) it causes fuse #9 to short circuit and blow. I thus loose the power windows and turn lights. I'm thinking that either some water has caused damage, or that in the process of removing the panels and working around the blower motor that I caused some wire damage somewhere. Or, perhaps the water permanently damaged the blower motor causing a system overload? My knowledge of automotive wiring is limited. . . Any input would be welcome. Thanks.
