you need more coolant. The reason the temp goes down when the blowers are on is because the engine doesn't have to work to run the AC and it vents the hot air from the engine.
My 2005 Mazda 6 S 5 SPD is hesitating during crank. I turn the key it waits about a second or 2 then cranks and has kinda a weak noise but runs fine. Whats the problem?

How do I change out the trim that goes around my center controls,I wanted it to be blue to match my exterior instead of the gray it is now. and how do I install a custom stereo if I want to cause it all looks like the air and sound and everything is one piece.
