I have a 2000 chevy blazer. I had the head gasket replaces 6 months ago but they unplugged my heater core thinking it was the core. It turns out it wasn't but they never plugged my heater core back in...my heater doesn't work so I have to replug it...where can I find it and what hoses do i plug back in to have my heater working again? Any suggestions would greatly be appreciated.

 

Check out the heater core flush article in the Tech Article (DIY) Index link found in my signature below. It will have pictures showing the location of the heater core lines at the firewall.

 

RRR... I hate it when links don't go to the right place, or ya gotta hunt!

 

What do you mean? How difficult is it to click, skim/read, and click again...?
