October 31, 2012The heater in my 2000 silverado will not blow hot air. When I first turn it on, it blows plenty hot, but then begins to cool and after a minute or two Is barely even warm at all. I have plenty of coolant in the system, and the temp gauge rises to normal operating temp as usual at about 200 degrees or so. Has anyone experienced this, remedy, etc?? Thanks

November 1, 2012I had the same problem around last winter going from hot to warm to cool. I replaced the therostat which corrected my issue.
