Hey guys I got a 2000 jimmy last night my blower motor quit working so today we replaced the blower motor and the 4th speed won't work anyone have idea what it could be.


Also unrelated while the blower motor was getting fixed we took a look at my 4wheel drive not working my cousin checked all the connections and we got the 4low to work buy not the 4 hi isn't working any ideas on that

 

On the 4WD question, start here:

Run the diagnostic, see what comes up.

 

Kinda curious about 4th gear on the blower motor. I just acquired my 2000 blazer not too long ago, I have the same problem with it. Haven't worried that much about it, but hey, if i can I'll fix it.
