My #4 setting keeps burning out on my blower swtich

1-2-3 fine. #4, even with a new resistor, and two new harness and plug, the #4 on the switch seems to overheat and melt the housing around it. Why is that? I am on switch #3. Again, yes, I swapped resistors and wewired new plugs.

check and make sure that you have the correct amperage fuse in the blower motor circuit, i think it should be a 15amp., double check for me.

Where is that? I wonder if thats the problem. You mean in the fuse box?

#4 dam ian wtf

it's not that cold man......what you trying to bake cookies in the car man.

just use #3 and when you sell the car dont say anything

my car only works on #4 ughh !!

only on 4 u need a blower motor resisitor....ian it is in one of the fuse boxes, i think the one by your left knee, may be under the hood if it isn't there

Motor drawing to much power? Could be on it's way out. Do you have a spare blower motor to throw in?

totaled200ser · 03-06-2005, 09:40 PM

possible but it should be blowing fuses if the correct one is in there i would think

All the fuses in the fuse box are the correct amperage.

Yep, you need a new blower motor , its bad and has high resistance..

totaled200ser · 03-07-2005, 03:37 PM

i'd also say swap out the blower motor if all in the fuse panel is ok

Funny thing is I replaced the blower motor 2 years ago. Back in the 90's, I used to kill blowers like it was no ones business. I realized it was the A/C drain tube that fell off allowing water/condensation to come back into the tube. Since, I have replaced the tube and the blower motor. Then a I replaced the resistor. The switch harness was melted on the #4 plug, so recently I replaced the plug with a plug off another NX and replaced the switch. So this one is bad again. What the hell???

Ok, today I trace back #4 which is blue with a white stipe to the resistor. The #4 at the resistor has green corrosion in it and a little of the insulation is stripped off above it. You think this could be a part of the problem? I am swapping and lenghting the plug to see if that helps.
My POPS (electrician) told me also that the fan could be drawing too much power as well.
