'98 Chevy S-10 Pickup heater blowing cold air

Szarafinski1: Thanks for your suggestion to my problem . concerning my truck blowing cold air with the heater turned on. To answer your question: yes my truck blows cold air at all three levels (floor, mid and defrost). You said there could be a "problem with the tempature door actuator". Where is this located, is it diffucult to replace and how much does it cost for me to replace? Are there any special tools needed to complete the job.

The temp door is located in a box behind the glovebox, the actuator is either under or above the box. if you remove the glove box you should be able to see it.

2004 chevy s-10 hater blows cold or lukewarm air


Well 1996 or 2004 is just a blend door to controll the temp.I see it also shows a heater core temp sensor on the 2004,but not sure if this would cause the problem.Your blend door allows air to pass over your heater core or just draw outside air.Well hope this helps.

98 chevy S-10. I turned on my heat one time, it made a weird noise then lost the heat and only blew cold air. After changing the lower heater hose, which was busted, I tried flushing the system and lost...


simply connect a garden hose to ether side of the heater core and turn on the pressure, it should flow freely, this is a good method to flush the heater core, then flush in the opposite direction

You need to check your coolant level first. If it is low you have a coolant leak. No hot coolant=No heat
