Thread: Air conditioner not very cold

  1. #1

    Air conditioner not very cold

    This is in my 2019 Mirage ES 5 speed. Manual HVAC controls, not the fancy digital one.

    So maybe I'm used to my old Chryslers and my Toyotas but the A/C in this thing isn't all that great. On the highway going 70 it can get really cold but it cycles the compressor so it won't stay that way all the time. Around town moving slow or idling it's definitely colder than outside but not refrigerator cold like other cars I own and the compressor still seems like it cycles a lot when it shouldn't. I was near the dealer I bought it and they checked it. Said ambient temp was 77 degrees and air temperature was 47 degrees coming out of the vent by the driver and also the pressures were okay. The service guy there told me the Neon's air conditioner was way colder than the Mirage and it's part of the system to not drag the little 3 cylinder down too much.

    It has an appointment with Biggers who seem to know what they're doing tomorrow. But wanted to check with anyone else to see if this is just normal for the car or if it's not right. I know a lot of Toyotas and Chryslers use variable displacement compressors so when they click on they literally stay clicked on ALL the time instead of cycling on and off.

    I had a few cars last week that had some ac problems. One car would just blow warm air, the compressor would cycle normally. It was just a little low on refrigerant. Another car blows warm air and doesn't cycle the compressor at all, haven't looked at that one yet.

    Rescheduled appointment for Wednesday. Should be the hottest day this week.

    I checked out the latest car, the lower(low pressure from compressor to evap) ac line rubbed a hole on the compressor pulley. This is the third car in a month that's happened to. The first had a torn belt that snagged the line and bent it towards the pulley, the second car hit something low on the passenger side pushing the rad support back bending the ac line into the pulley. The third one, has no signs of hitting anything but I think the belt split a few months ago and could have bent the line at the same time?

    I'll make sure to check that but it's only got 6700 miles on it so it better not be broken in that way haha

    We've heard from a few owners that their refrigerant levels were very low from the factory. I checked mine a couple of months ago, it had a very low charge. Recharged the AC myself for $25.00. My AC compressor is much quieter now, doesn't cycle as much, and blows colder air. But living here in the ever so mild Oregon Coast I only run it about once a month to keep the compressor oiled. There are the 4 or 5 days all year where AC might be nice.

    Hmm... well I'm make sure to make a point to that to Biggers so they know. I don't think they sell many Mirages (mostly SUV's) so they're not aware as much of the goofy issues they have. I get heat sickness especially when I'm in the car so good working air conditioning is a must for me.

    Great points to know! Even if you don't feel comfortable doing the work yourself, it's nice to point your mechanic in the right direction.

    Biggers said the system was low so they evacuated it and recharged it with some dye in the system to check for leaks. It still doesn't work that good so back it goes tomorrow.

    Okay, checked for leaks. None. Service staff tell me it's working about as good as it can. I ask if the mirage just has a weak a/c system and they said the condenser is pretty small...

    So yeah, apparently that's just how they are. Dammit. I can't imagine the thing having a chance in hell cooling the inside when it's 100 degrees and muggy out.
