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.

Questions:

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.
