Re: Baby it's cold outside
Flush the heater core. Probably more than once, its a known issue with S10s.

Re: Baby it's cold outside
Back flush the core. Remove the lines from the system. Use a water hose to flush it really good.
Does it blow air? Check the vacuum line under the hood. The line connects to the vacuum ball. |

Re: Baby it's cold outside
dontcha just love dexcool?
I hope you didnt put a long screw in the hole behind the blower resistor. if so you will be stuck on hot and possibly ruin a door actuator. |
