Lost blower setting #1, then #2, then #3.....only 4&5 working right now. Time to fix it!
I know this car very well, it has been well maintained but: a few years back speeds 1,2, and 3 became inoperable. This past summer speeds 4 and 5 went out with the exeption of random operation only to quit seconds later. This has me second guessing everything I thought I knew. I replaced the relay and of course it didn't change a thing. The motor made no noises and operates too smoothly to be the culprit....? I'm stumped.
Just stop working 1&2 went out now 3 4 an 5 did
blower not working on setting 1-2 and now barely blowing or not blowing on any setting
Speeds 1 and 2 quit working
replaced resistor
motor only works on hi setting 4 & 5
