2003 envoy xl 4wheel drive keeps over heating

That code represents a lower than expected reading for temperature (coolant). First thing to do is check your coolant level, as if it is low, then the sensor can not read correctly. Second, you may have a thermostat that is stuck open, allowing the coolant to cool off too much. The sensor should be mounted on top of the engine, near the thermostat housing.

RE: Oil Pressure going UP & Down!
I'm going to assume you had someone or a shop change your oil.
If you did I would immediately take your car to another place as your oil gauge should not be doing this. Worst case is you have an oil leak so check your oil immediately and add oil if necessary before driving.
Most likely someone put in the wrong oil filter and your oil is having trouble circulating since this is a fairly new car!
Also, if your oil was overdue a change.....have it changed again to clean it up as this could just be it's still dirty and clogging the new filter.
I wouldn't worry too much if your oil dipstick is showing it full!
But do a follow-up asap!

Need to check to see if the blower motor is running.If it is,but not threw the vents,most likely a vent door actuator motor.The actuator motor in this case would be bad,it is hard to get to,unless you are mechanically inclined,You can do it your self.If the blower motor is bad,just replace it.Check fuses first,and the blower relay.If I can help,let me know.

Try disconnecting the battery for a few minutes, that might get you out of trouble for now. There are some common problems with these 4wd systems. Most common is the mode position sensor on the encoder motor. Sometimes it can be the switch on the dash. Fact of the matter is I can't tell you what is wrong without using a scantool to retrieve the fault codes from the computer controlling the 4wd.
