Still some Mitsubishi trouble. Part II

AC Amiture on Mon June 16, 2008 3:49 PM User is offline

Year: 2000
Make: Mitsubisi
Model: Mirage
Engine Size: 1.5
Refrigerant Type: r-134a
Ambient Temp: 108-120
Pressure Low: 47
Pressure High: 295
Country of Origin: United States

I had a chance to look at this Mitsubishi again tiis weekend.

My daughter says that occasionally "It wil start blowing hot air like it is just coming in from the outside."

I drove the care for 10 minutes (By my watch) while the ambient temperature was 108 in the shade and 120 in direct sun. My thermometer showed a vent temp of 55-58 Degrees during the 10 minutes. This is not as cool as I would like but not bad. The system, at best, will only give 46-47 Degrees in the evening and cooler with no or little sun.

The air seemed to be cold, then occasionally it would be a little warmer but not hot and the vent temp stayed as described.

Gauges were funny when I first hooked up, showing Low of 55 and High of 320. After running a few minutes they were more normal Low 47 and High 295.

She insists that it will start blowing actual "hot" air if it runs long enough, then cold again.


Does what I was able to observe sound normal for these cars? What would cause it to occasionally start blowing "hot" What should I look for if I can get it to blow hot?

There is a possibility the the evap core is freezing up. Does she think it air volume slows down out the vents when it gets hot? Also a chance you are shutting down the system do to a high pressure issue.
