2004 Vue AC repair

[lupi]

Recently noticed the air in the vue is coming out of the vents at 70ish (judge by feel, haven't gunned it). System pressure in the upper end of the normal band and the family mechanic had the vehicle for awhile to look at the system and thinks it is the compressor going bad. Ac system top of my no little about list, so is there anything else that would be a likely culprit?

Typically, if it fluctuates at stop/idle, that can be low coolant. But probably not your culprit as that doesn't seem to be what you suggested.

Could be low coolant due to a leak. Fix leak, add refrigerant and try again.

I don't believe your vehicle has the same issue with blendoors that some older Dodge/Chrysler vehicles have.

Or, compressor.

I drove it a bit before giving it to him and it was a constant warm room temperature.

Is the A/C compressor kicking on and running?

It's almost summer again...

OP, if the pressures are normal, then it wouldn't need a compressor. Generally, to diagnose a bad compressor, you need to verify the level of refrigerant (i.e. evac and recharge by weight), then observe a normal rest pressure, but a low side that's too high, and a high side that's too low.

Verify that all the interior air doors (blend, recirc, vent) are working normally. And/or simply check the lines going to the evaporator to see if they're cold. If the inlet is room temp, then you're either undercharged, overcharged, or your compressor is making a noise indicative of something about to explode.

This also assumes you have physically observed the compressor working (obviously, observing pressures should tell you if/when it's coming on) and also verified cooling fan operation.
