Add these two value f resistances. Again, worked like a charm, but per usual, on setting two I got a glowing coil in the resistor. Why does my blower resistor keep going bad. I replaced the wiring harness to the resistor, as on one of my burnouts the original completely melted down. I left the harness in place because I felt if I took it off right now, I might forget how to put it back on by the time the new one gets here. They work fine when I first turn them on, but after 10 minutes or so, they will get hot and some will flicker and eventually turn off. Or the cowl panel is not sealed well against the windshield. Asked by in Connersville, IN on . But I see you also have a 180Ω resistor in series before the (shorted) BTA136 Even if you include the 180 in series with the 470, that's still 184mA @120VAC = 22 watts. My issue is that the LEDs appear to be getting very hot, and are slowly burning themselves out. With the setup you have, the resistor dissipates about 2Watts. Method 1 Scarp the outer coating. 2 years ago my original motor went out, bearings started equaling and seized up, and it took out the resistor too.So I replaced the resistor and motor, and a few weeks later the new resistor and the connector on the harness were burnt out. I did this under the supervision of an electronics technician at a bench job I had in college. :lol: I might need your help again once they get here. It's actually unlikely your resistor would explode if it's rated too low, but it probably won't last very long, and will burn through due to overheating. BUT I am having this same issue. I pulled out the resistor and sure enough, it was burned on the right hand plug just like everyone else. Why does my blower motor resistor keep burning up in my 2001 Dodge Dakota? Depends. 3. This is the approximate value of burnt resistor. So, since doing all of that, I replaced the resistor to try my new relay setup on all 4 speeds. Most "off-the-shelf" resistors are rated for 1/4 or 1/8 Watt. Clean the burnt section of the resistor. If the blower motor looks like it is rusty, or the resistor keeps burning up, then it is most likely water intrusion. Measure resistance from one end of the resistor to the damaged section. When the resistor is working, it reduces the amount of voltage going to the lower fan speeds so the fan runs slower. Again measure the resistance from damaged section to the other end of the resistor. out of yourself on a resistor….a tiny little resistor. Yeah, every resistor in that circuit will burn up. I'm ordering the new one right now. Yes, it is possible to burn the $#*&! A quarter watt resistor should light up like a light bulb. Albeit very briefly. A usual place for water to enter into this area is a loose, or missing weatherstrip under the upper cowl panel. The diffuser is very hot at that point. January 17, 2018. Burning Yourself on a Resistor. I have replaced the resistor and wiring harness about 6 times in the past year? I have put a new blower motor in and new resistor but yet 2 days later it burned up again. 2001 Dodge Dakota. ...
