AC blows cold then warm then cold again
Hey everyone
so my ac is acting strange.. It will blow Cold air, then after 2-5 minutes it will start to blow warm air for a few minutes, then blow cold air again.. its kinda like a pattern. The compressor is on and moves and there is enough freon in the system, so not exactly sure what the problem is..

This post may help you, they appear to have a similar issue. I had this issue with my Honda, turns out the AC system was over charged from previous owner.

What I'd want is the exact charge prescribed by Mitsubishi. That requires taking it to a shop, having all refrigerant extracted and then charging with the book amount of refrigerant with dye. This should cost you about $120 but then you know, if the system continues to act up, it is not due to refrigerant and you need to look elsewhere.

If the compressor grenaded and scattered metal throughout the system, that might be the only choice. One failure very common to the Evo A/C is the clutch wearing out. The clutch is good for about 100K in moderate climates, if you live in the South it could be a lot less.

I have 143k on mine and it still works. I did however have to get the washer kit for the clutch. It wasn't working and it ended up that the cutch was too far for the magnet to engage properly. The forums helped a lot with solving that issue!

SAFELY would mean attaching proper hoses and evacuating the R134a out of the system into a holding tank. The careless alternative is to let out refrigerant into the atmosphere little by little until your system balances out (illegal). Nobody who matters cares about the environment anymore anyway so whatever. Without knowing the proper ounces of R134a, compressor oil and condition of other associated A/C system parts, it's kinda like a guessing game.
Most common A/C issue with these vehicles is the air gap on the compressor clutch narrowing causing intermittent A/C issues.

How did you take a second look? Through the window on the line or evaporator? Without an A/C machine there's little to no way to tell if your system measurements are off (oil, refrigerant, etc.)

I bought one of those recharge bottles that had the gauage at the top.. Without putting any freon in the system, I just checked the current pressure and it was high.. I guess I'll just have to bring it to a shop that can get it out safety.. Or just bring it to the stealership because while the fix the new recall issue
