No Heat while driving 2003 Laredo
It's getting cold here in Indiana and I need to get this fixed, quick!
My vehicle starts fine. Idling there are no issues. The temp gauge rises fine to 210 and heat comes from whatever vents I choose without any issues.
However, once I start driving the air comes out, still in full force, but the air temperature drops drastically. The temperature gauge also drops. Last night driving home from work, it was about 32 degrees out and the temp gauge was bottomed out at 100 and nothing but cold air was coming from the vents.
Coolant levels are fine. I changed the thermostat about 2 years ago (doesn't mean it's not bad).
I am sure this is something that I can handle, but I am unsure on where to start to try to fix the problem.
Thanks in advance for your help!
