Hello every one, I had a Accord 2014 EXL and The AC stop Blowing Cool Air, after check everything else with 3 mechanics; they can't found any mechanical problem everything pass the test, and finally this error came out U0155, AC SUB DISPLAY LOST COMMUNICATION WITH GAUGE CONTROL MODULE.
I need and expert help, where I live the temperature start raising to the lower 90s and I need the AC working.
I appreciate the help to resolve this issue.
Thanks

 

Was work done on it prior to messing up. You may want to start checking the fuses under the dash. Your PCM can not communicate with it

 

Check the #5 fuse under your dash. If it's blown try to replace it. If it blows again you have a short somewhere and need to find it. Could be a bad combo meter

 

Thank you for your advice, but all Fuses including the ones under the dash are ok. Don't know what else. what is the Gauge Control Module?

 

Thank you, where is the PCM and how to test It?

 

Just a guess, but if it didn't blow a fuse, you might have an open wire or loose connection.

 

The gauge control module is part of the circuit board of the gauges like speedometer, tachometer, etc above your steering wheel. The A/C sub-display is a control module that is part of the circuit board where you control the climate in the center console.

It sounds like the gauge module isn't communicating with the a/c panel. The problem can be the gauge cluster, the a/c panel circuit board, or the wiring connecting them. Was any recent work done on your car before this problem happened?

You said the a/c isn't working, but tell us more about your observations. Can you control the blower speed, does the a/c panel appear to work (like changing the temperature, turning on the a/c, etc.)?

 

Thank you for your help. YEs I can Control all the commandos in the AC panel everything respond, but when I turn the AC ON shows that its ON but only blows hot air.
My mechanic check everything and he said that he didn't find any mechanical problem, but when I run a check throughout the OBD shows that Error Code U0155.
I don't want to go to the dealership because everyone knows how they are. $$$$.

 

You didn't answer my question if you had any work done to the car before you had this problem.

Do you own a code reader that is pulling the U0155?

When you attempt to turn on the a/c from inside the car with the engine running, does the a/c clutch engage and start spinning with the a/c pulley?

 

No work done, to the car at all. When the car is running and press the turn the A/C on, the screen show me that its on; but the A/C don't engage at all. I don't Own the reader, I went to the auto zone shop in my neighborhood. they give me a paper with the reader report Code.
