I have a strange issue with my AC. when the car is stationary, no problems. While rolling it will cut in and out. It will blow cold as hell for 5 minutes, then then it just stops blowing cold air. It still blows but not cold. Shut it off, and back on it will work again. Today I had to drive 500 miles. there was a stint when it stayed on for about 2 hours, then just cut out.

Anyone seen this before, of have any ideas? About 2 years ago, I did have a fuel injector resister on the firewall corrode through one time, and I am thinking this could be on the same line of problem.

I really appreciate it anyone has some thoughts on where to look.

 

check r134a might be low on it. if low recharge it. if not that check the compressor clutch coil.

 

^^ I should have mentioned that earlier, I am sorry about that, but i did have that checked out and it was spot on.

 

I have this exact issue right now and have been meaning to post about it, there is a repair kit that mitsu sells for the compressor I think I'm going to try, I think it may be a compressor clutch engagement issue. I'm sick ofswearing my ***** of so I think for the $25 the kit costs it's worth the try. BTW, my r134 levels are also good. When it stops blowing cold air I can see the compressor is no longer spinning

 

^^ do you happen to have the part number or anything? I had to drive over 1K miles in two days and and am tired of swetting by bag off too. its like 100+ outside.

 

MR315936 AC clutch service kit

 

is it common problem?? i guess that i have a same problem now. i had that happen just one time since i drove it.. i dont want to get any problem when i drive my car thats way i took my car to the shop today. not the dearler shop..
and they told me that they gonna check the leaks and freon gas for AC
do i need to check ac clutch kit first if they gonna tell me that i need new ac compressor?
thanks..good info

 

Yes, compressor coil.

I finally got it to not work one day and found it was intermittent coil operation.

 

Fairly common. I just shimmed my gf's Evo on Monday. Removed the .024 shim and installed the .019. All you need is a wrench, calipers for measuring or just "eye it" and a screwdriver to keep the plate from turning.

 

About how long would you say it took? Did you need to remove the belt? TIA!

 

Same problem. Will try the kit then update.

 

The belt doesn't have to come off at all.

 

re shimming might work not work all the time. as if the coil is bad, it will over heat and will cause it to disconnect the ac shaft. to fix the problem properly you have to replace the coil. re shimming is a temporary solution ( although i do understand that it has worked well for some people on the forums ) .

 

Shims have worked for several members on here, just check the gap and go from there, https://www.evolutionm.net/forums/ev...ng-advice.html good info here

 

Did you ever find the problem newimportowner? and was it the compressor coil?
