I know, I know! Why would you need it now (summer time, 100+ heat outside). But winter will be on it's way sometime.
I put it on defrost (fan on), temp switch on "heat", A/C switch off (engine heated up good, 200 ). Just cool air coming out the vents (vent doors are working correctly). If I turn off the fan for a bit, then turn it back on, I get a small burst of heat. Then it goes right back to blowing cold. My heater core is not leaking (no wet floor, no smell of coolant). I'm thinking the core is plugged up a little (not letting the coolant flow through enough).
I did find this on you tube.

Seemed to make sense to me, I'll give it a try. Just wondering if anyone out there has been down this road, tried this, and if I'm on the right "diagnostic" track or have suggestions before I do this?
Thanks
