Well first it was my wipers, fixed that with a new board & next day my heater wouldn't blow hot. It's a 95 GMC 4.3 V6 vortec. I replaced the thermostat about 2 years ago with a "Failsafe", but went ahead and replaced it today with a "Superstat" from NAPA, and still no heat. I checked the old one in a pan of boiling water today & it's opening. So,,,, these couldn't be related, surely. But that's my luck. I mean,, it's just like my heater was goin bad while I'm working on my wipers. I might try flushing it out tommorrow & letcha know how that goes. This heater thing is really puzzlin me. I'd appreciate any ideas Thanks Richard
