I have a 2001 Chevrolet Blazer with approximately 90,000 mi. Randomly I will lose the heater functionality. For about the last month I could turn the nob to RED (hot) and turn the fan to the highest number 4 and I would at least have some gnerally warm air but not a strong or hot stream of air. I can change where the air flows (eg floor, vents, defrost) and feel that the air is going to the right duct. The last three days I have turned the heater to HOT and the fan on the highest speed and I have cold air (temperature of outside) blowing through my vents that is not very strong at all. When I leave it on the highest fan speed with the hot temperature, I will never receive anything remotely warm but my temperature guage on my dash dropped from 210 (the normal running temp) to 150 in the matter of 5 minutes. My radiator was just flushed two days before this reoccuring problem started back up again. Any suggestions as to dropping temperatures, low blowing power and no heat? Thx sooo much in advance!
have the same problem?
