Wierd Heat Issue...

[El_Cid_2000]

I had the heat on this morning and stopped at the Sunoco for coffee. Got back in the Rover and the "heat" was ice cold; like the A.C. was on. The truck was running fine and it started right up fine too. Any ideas? 97' D1 144,xxx miles.

I'm just now getting off of third shift so I'm not going to look at the truck till' after I wake up ths afternoon. Anything I need to look for or at?

Check the coolant, see if it's running low. Also check for possible blockage going to or from the heater core.. That would be where I would start.
