I hadn't driven my 74 2.0 for several months due to work on another project. Took it out yesterday and it felt like the heater was on full blast, plus it smelled like exhaust in the cabin. Top was on ant it was a hot day but I've never experienced that sensation before. The heater controls were in the off position.
When I restored my car a few years ago I pressure checked the heater boxes an they were good. Any ideas? Thanks, Jack |

Could be a stuck heater flapper box, or heater cable. I've seen the flapper box stuck open due to a broken impeller blade that worked it's way into the flapper.

I pushed the stainless steel connector tube that attaches to the flapper box too far into the flapper box. This wedged the flapper open just enough so my passengers would have heat on their feet in the middle of August in Florida (IMG:style_emoticons/default/blink.gif) |
