2001 Sonoma Heat Problem

[kplourde]

I am wondering if 48.5c coming from the air vents of a 2001 Sonoma is normal on a 25c day driving on the highway (100km) with the windows down.

48.5 is pretty high, Where are you checking the temp? If you left the thermometor on the dash on a hot day I could see it getting to 48C.

How does the temp of the engine look?

I thought when the thermostat goes it means that there would be less heat? I would still check it is it is easy to do, stupid question, but do you have the heat up on the controll dial?
:dunno:

The Thermometer is at the driver side feet vent. Temp of engine is fine says the controls.
