2002 Chevy Blazer Heat heat problems
 

I have no heat! When I did a diagnostic a code comes up for a Massive air Flow sensor. Does this have anything to do with having no heat? I saw another person on here with the same problem of no heat and the heater core was clogged...... i think this may be the same problem with my blazer. This person had it un-clogged with a garden hose. I would love to try doing this myself if possible because lord knows I can't afford to have it done professionally. Any pointers? Its getting cold here in the Northwest. I can deal with no heat in my car but I dont want my kids to freeze. Please any advice would be great!

It is doubtful that the two are connected.

There is a lot of information available on the forum concerning flushing the heater core. Run a search for "flush+heater+core" and read up!
