Wheres the coolant temperature sensor on a 2008 gmc acadia?


Usually located near the thermostat housing, screwed into the intake manifold. Should be two sensors, one having only one wire feeds dash light, one with two wires feeds computer to adjust fuel mix depending on engine temp.

My car says engine hot A/C off


If the engine overheats, the computer will turn the ac off. However, on GM vehicles, the thermostat can be bad, not letting the engine get warm enough, and causing the same problem. I would replace the thermostat.

At 45 F that is just 12f above freezing and it is possible that the thermostat inside the car is turning the compressor off as it is intended to do. I suggest that you take it to an accredited ac specialist shop for pressure test and thermostat setting test.

Why my acadia its blowing hot air when a/c is on


several reasons why ac not blowing cold. Most common a freon leak causing system to be undercharged. electrical and component failure may also be a factor. You need a set of gauges. find the compressor start engine with a c off the compressor clutch wont be engaged now turn it in on and see if clutch engages. If it engages you need to know what your low and high side readings are. You should have your system diagnosed be a seasoned pro...... If clutch does not engage you probably are low on freon. Put dye in the system so you know where the leak is when it leaks again. you can buy freon with dye already in it.

300M WARMS UP TO NORMAL TEMP HEAT BLOWS HOT THEN AFTER ABOUT 10 MIN. ON EXPRESSWAY HEATER BLOWS COOL.I TURN TEMP UP TO 80 AND GET HEAT AGAIN.


this can be 2 problems the thermostat
or the module pcm that controls the digital controls on the dash panel
this is for the ac and the cluster if you change it you need to ask them to write your milles in it
i got one for a town and country and fix the ac problem anf it also give me 80k aditional miles

do the dance key test
you open and close the ignition key 3 times and the cluster will display error codes from the computer
with the codes we can solve this problem
