I have a 2003 chevy venture with 64, 00 miles it has a 3.4l engine the air blows about 44 degress on fan
speeds 1 & 2 but the higher the fan speed the higher the temp. Up to 70 deg. On high. Where should I look first.
I don't understand those temp differences, Does the engine temp fluctuate up and down like that? Does the temp on the heater hoses fluctuate? I'd have to check temp door to see if it moves with blower speed, for some reason.
