i think this was covered by another post but mine seems to be a bit different. i've noticed my temo guage registering just below the half-way dot on the register while driving but sometimes it will drop to half that. when this happens the air blows colder. i'll reach up and hit the top of the dash a few times and the guage and heat go back up. also, i've noticed when i come to a stop, the heater will sometimes blow colder until i start driving again and then warm up. the guage doesn't drop when it does this. **when the heater blows colder in both of these situations, it doesn't blow colder by a large margin, just enough to let me know that it is colder. any suggestions??

---i've checked the coolant/anti level, checked to see if the coolant/anti is filled enough and seems to be (has the nice neon greenish look),.....

thanks for the trouble...........
