Freezing, need heat, help!
First off, family man w/ kids. I need my heater. Ok, before I thought to bother the forum, I chose to read all threads I could find relevant to my problem. 98 Laredo, inline 6. Blowers are working fine, just blowing cold air. I checked the heater hoses, both are hot so that should rule out a faulty thermostat. The linking rod underneath the dash is attached and working properly. I took off my dash to examine the blend door. It appears to be working fine. In the off position, door is open. when I switch heat to on the door closes, so it appears operational. The only thing left to check that I have read about would be a clogged heater core, or it need flushing or replaced. However, I cannot find step by step directions on how to flush my heater core. Where do I even start? Advice and guidance is greatly appreciated, thanks everyone.
