Definitely a short circuit......somewhere along the line in the heater
circuit a hot wire is being exposed to a ground connection. Could be
caused by a loose/broken wire, shorted motor, short component etc. Try
looking for burnt components, loose wires etc. Sounds like the short is
bypassing the fuse compartment too...wicked! :-)
Yeah it doesnt blow the fuse, it just gets the switch and wires going to it
hot, REALLY hot and it smokes a little, doesnt catch on fire but as soon as
I kill the heater fan switch it cools right back off. The fuse in the fuse
box is also the reccomended size of a 30amp. I didnt up the amps because it
blew before or anything stupid like that.
look under the steering column and see if the cover is starting to melt. If
it isn't you may want to remove the cover and inspect the battery and ground
wire at the switch for looseness or burnt.
Your talking about the "box" that is directly below the ignition key
itself? If so, no it isnt burnt yet, but when the blower fan is on I cannot
touch that part at all, and the wires going to the switch arent burnt either
yet, I think I've caught it soon enough that it hasnt damaged it to badly
yet. Now one other person told me about a HVAC Blower Switch that could be
bad any possibilities? Also is there some sort of recall for this?
Without looking at the car my guess is that the ignition switch is causing
the problem, it feeds the blower and everything else that is on the
accessories side. The blower motor draws the most current and I think that
is why you are getting that affect thru the switch.
I can remember replacing lots of those switches when they would come into
the dealer and repaired many burt/loose connection there also.
No ther is no recall out.
