Howdy!

ItÆs probably the Heater Fuse û or maybe the Blower Motor itselfà

Even though you donÆt see any signs of leakage, go ahead and remove the Blower Motor. --- You might find that a recent heavy rain has snuck its way past the cowl shroud and into the intake duct - thus drowning the motor and/or blowing the fuse.

With or without the presence of water, a quick test of the motor will let you know if it needs to be replacedà If it passes the test, the problem is almost certainly the fuse (itÆs an easily overlooked rectangular black plastic thingamabob - about 1 inch x 2.5 inches, with a Philips-head mounting screw on each side - located on the heater core housing, immediately to the left of the blower motor). --- IIRC, there are three connection points on the top and bottom of the fuseà if any of them are missing / melted away û BINGO.


Just so you know û the parts stores think mighty highly of replacement Fuses and Blower Motorsà IÆve been running one-of-each for a couple of years now (that I bought at a junkyard) without any problems at all.
