low blower speed doesn't work
I have a 2006 F150 and my blower doesn't work on the #1 setting. Usually if the resistor goes out doesn't it blow at high speed? i have speeds 2-4. i tried a new switch but it still doesn't work. Is my next step a new resistor or am i missing something?

i just pulled out the resistor and it looks like a big microchip. the only speed that worked with it unplugged was high. i know that the #1 setting blew air before. is there a way to check that kind of resistor?

yes check the resistance of the resistor lol
4 pins correct?
top
1 2 3 4
top being that is where the clip is the bottom is flat
resistance of 4 & 2 2.0-2.6 ohms
" - " 2 & 3 .2-.4
" - " 2 & 1 .8-1.1 ohms
if they are not in spec the risistor is bad.
if they are you have a blower switch or wiring issue
