Hey! My Tacoma's heating system isn't up to snuff. Specifically the temperature of the heat. The fan speed is good but it seems like the fan is blowing through the heater core so much that it cools it down. I just had the head gasket recall done last year. I had to put in a new radiator, cap, and thermostat also. Even though the opertaing temp is good the heat still doesnt blow very warm. I'm not sure if the blend door is acting up or what. I've also got a little air in the system. I tried burping the system by raising the front end and running it with the cap off. Unfortunately It was too cool that day for the engine to get warm enough so I got impatient. Anyhow, if anyone has this same problem or remedy I would appreciate a post.
