Probably the air condition system has a low gas alarm- requires check for leaks then re-charge.
The low pressure gas switch disables the A/C clutch control.

How do I disable the srs airbags so I can safely work on wiring under dash (installing a remote starter)? will be rearming system when done.


check your service manual dont have one? get one.

there should be a RELAY (1" saquare block plugged in like fuse in the relay box) to control them. but you must check service manual first. some systems unplugging the relay or plugging in the relay may cause detonation. you need the service manual if you want to mess with airbags. please do that.

Driver side airconditioner not working passenger side work s great


The vent passages of the ac system has shutters (direct the path of the air flowing through the system) internally that are either electrical or manual when it comes to movement. So, if one of the shutters or how they are manipulated fails/breaks, your symptom can arise. A manual with how the vent passages are laid out can help you pin point the location. Lastly, it could be clogged with something.

2003 Hyundai Sante fe A/C fan and rad fan not turning Fast enough while A/C is on but work OK when engine come to temp. ac starts off cold then gets warm after about 5 miles.


make sure radiator and or condensor fins are not restricted with dirt , bugs etc. poor airflow across the condensor. high side pressure could rise too high causing compressor to cycle off and on and not cool the freon properly.not sure what you mean when you say you play with the relay and it comes on. compressor or the fan? pull the relay and look at the female pins and make sure they are not spread open too wide. is the check engine lamp on? sometimes computers will disable ac for some other faults. im not sure if you mean the compressor is turning off and staying off, or just not cooling well due to fan problem. if its turning off it could be a control head problem or the pcm disabling it for another reason. or if you are manipulating the relay then compressor kicks on you may have a bad relay. hope this helps

Ihave problem whit the light pop in the dash the air ride is on all teh time,i am look the manual an try turn the suicht on and off of the trunc is not work


Hi Alejandropen

Your Check Suspension light has come on for a reason and turning the on/off button will not remove this problem.

If your compressor does not come on

Go through the basics with the system starting with its power. Check the fuses for it in the engine bay fuse box.
Also fuse 1 and 4 in the car fuse box locate dnear trunk release.

Replace if blown and see if system works.


Checking compressor

Pull out the relay for the air suspension in the fuse box in the engine bay.
Pin 30 is the one located directly under the fuses above it.

Pin 30
Pin 86 -------- Pin 85
PIN 87

Put a peice of wire between 30 and 87 the compressor should come to life IF its workings, dont hold this bridge in for long just breifly to hear it come on then stop it.

If this works try switching the Horn relay to the Air suspension one and see if it comes alive.

If this does not work and all the fuses are ok, You have a problem with the air compressor and need to pull it out for testing or replacement.

If this works you may have an issue with the suspension controller.

Hope this helps

Hi i have the exact same problems with my 94 accord ex


your problem is more complex then faulty gauge cluster as your cruise control doesnt work leading me to believe you need a new speed sensor its located on transmission and your lights could be faulty fuse, switch, or bulbs all of which are easy to test heres steps basically following repair manual ex:haynes or chiltons
1. troublshooting:
test fuse, relay, then switch heres how:
well fuse is no brainer but from there locate relay in electrical system section and test once light switch is activated if power is coming out of relay use schematic in section to find appropriate color wire
then if so pull lighting switch out from dash(carefully using skinny flat blade screw driver
then test to make sure power is coming in and out of switch (refer to color schematic)
if so pull gauge cluster do not unplug power leads test to make sure power is coming into illumination circuit (refer to maual) then if so pull and check bulbs (refer to manual) and replace and your done dont forget to rate me heres some bonus information for saving money on parts and accessories
