Ac light

[armallard]

My wifes car '05 Buick Regal v6 the last night it was warm she tried the ac and it wouldn't come on now I notice the light is not coming on I fuse? The reason I'm asking and not doing is its hard for me to get down and look since my stroke so i'm going to have to walk her through it the fuse panel lid I found the havac one and she said she changed it but nothing.Any help appreciated

Which climate control system do you have. Manual dual zone or digital automatic (ACC-CJ2)?


Note: The OP has a 2002 Regal.

I'm not in the car much so I really don't know how can I tell ? The motor is a 3800 seriesII

[armallard]

Its adjusted according t o what the degrees she wants she actually don't hit a button for heat or ac seeing now it won't go below 60 degrees its colder than that outside. I've looked all over and can't tell which one it is.

[armallard]

Ok her car doesn't have a light just turn it down to where u want it to plus the compressor is not kicking on nor trying I'm going to attach a pic of the inside unit maybe this will help

Does the temperature display flash for a couple minutes after you start car?

The temperature display is where you see the 70 in your photo.

If so, you have a code set. It would be good to know the code.- you can have it read

[armallard]

No it don't I just checked it, ran it down to 60 but never got cold. Any other ideas. Appreciate all the help I could get.

[brcidd]

If you are in "auto" mode and you've dialed up 60 degf and it is above 60 deg outside, then you should hear the compressor come on and feel cool air out the vents, if not, then time to get the a/c checked- for pressures and electrical issues.

I want to thank everyone for their input on this looks like its beyond me time for a cert. mech. again thanks

Is some kind of fuse box under the hood for the air. The compressor is running no cold air and al this happened all of sudden

Yes. The AC clutch fuse located in the engine compartment fuse box and a relay. However, the AC Clutch will not turn on if the system is very low on R134a refrigerant. There is a low/high pressure switch in the system for compressor safety.

[armallard]

No fuses under the hood are blown the clutch is fully kicking in when she kicks the thermo down. I put a code reader today and it showed two-------p0102-----p0128 when I looked them up myself I don't think it has anything to do with the ac,

[BNaylor]

Neither DTC is relevant to your A/C issue. One is MAF sensor and other engine temperature related. So to recap you are not getting any cold air from either the driver or passenger vents since it is dual zone? Have you checked your refrigerant charge at the low side port?

[armallard]

I gues I'll gave it checked with someone with gauges because as long sd she has it long its(clutch) fully ingaged

[BNaylor]

Thats sounds like a good plan to me and good luck!
