Thanks for looking...

Fall is coming and I went to use the heat on our convertible - got nothing but cold air. It worked fine last year. I went though the Troubleshooting suggestions in the 1967 FSM and found nothing wrong: Blower works, the water flowing to/from the core feels hot on the hoses, the damper that directs the hot air seems to work, the airbox damper arm moves properly, the control cable is intact.

What would you check if you had no heat from your heater?

Can a heater core get clogged? My radiator fluid isn't ugly or anything..

I'm a little stumped. I think I'll just keep checking the FSM and everything again, I think I tried all the modes; floor heat vs defrost, but I'll keep checking..

Looking for any and all ideas. ....Drill some holes in the firewall..? smile

Thank you,
