Hi all
just joined your Forum as this is my first Blazer
It is a 2001 2wd with a 4.3
my problem is the A/C-heater blower motor
I have replaced the resistor and switch, but it still only works on high.
the parts place said there is no relay,
many ideas?
Thanks

 

There should be a relay under the hood, on the firewall, but if it isn't working, all blower speeds should work EXCEPT for high.

 

General ChatChat about all things Blazer (and related vehicles). Off-topic stuff should be in the lounge, and all mechanical problems should be posted in the proper forum.

I suspect that the second generation forum or electrical forum will get you more responses.
