I have a 4 door 2002 Chevy Blazer. Last summer I started having problems with the vehicle running hot and shutting off when I would be at a stoplight or stopsign. Shortly after, it began to run hot and shut off while I was driving, over and over and over! It will start back up everytime though. I also have a lot of brown sludge in my radiator, which has been flushed out ... Read More...

I know this sounds stupid, but are you sure the cooling system is full? Each of the issues you discribed can also show up with air in the cooling system. When you accelerate hard, do you hear gurgling in the area over under the glove box (heater core)? Read More...

Thanks for your reply, I'll look into the damper. The temperature gauge has been going higher than it normally does, more like it's about to overheat, until I hit the interstate and begin to accelerate, then it lowers back to normal. Read More...

Julie, there is an air mix damper in the ductwork under the dash. I haven't had to work in this area, but it does sound like it could be your problem. These vehicles do not have the conventional heater control valve, so water is always flowing through the heater core. Anybody who has done work on this feel free to jump in here. :) Curious about the temp gauge, though. ... Read More...

How many miles on the Blazer, and has the antifreeze been changed and cooling system flushed. Very important, this vehicle uses the long life Dexcool antifreeze and cannot be mixed with conventional ethalene glycol (the green stuff). Read More...

Help, My heater only works sometimes. More specifically, the blower works but only blows cold air. When I don't need the heater, it works just fine. The temperature gage occasionally reads high. I have also noticed that sometimes, when the fan switch and the heat/AC/Fan selector switch is turned off, there will be heat coming out of the vents (small amount). ... Read More...

Well glad it worked out for you...you were probably right..a partially restricted filter, low fluid, missing seals...could have been any of them. Read More...
