2008 Civic Hybrid Air Conditioning
Here's what I know: The air compressor will not kick in, neither the radiator fan or the condensor fan will run. They both are good (I've checked) and the relay has been changed out. The blower fan runs fine and the controls appear to be working correctly. All fuses are good and the pressure sensor checks out. What I don't know- Why? Any help would be appreciated. Thank you.

If you think a good mechanic is expensive, try hiring a bad one
Re: 2008 Civic Hybrid Air Conditioning
How much pressure is in the AC system?
Is the thermal protector open circuit?

Re: 2008 Civic Hybrid Air Conditioning
Thank you for responding ezone. The pressure is good for not having the compressor kicking in...enough that the clutch should start kicking in. no leaks in system...and thermal protector checks out. The clutch is good, coil is good, and air gap is good.

Someone posted in this forum after attempting to jumper some wires at that sensor, turns out he ruined the PCM by doing so.
There's 2 immediate directions to choose from.....either the PCM checking for data and info, or the HVAC panel to do a self diag check.
First place I'd go is to the PCM with my scanner.....
What does the PCM data list show the system pressure as?
Are there any PCM fault codes? Transmission fault codes?
Does the car have any IMA system related fault codes?
What is the PCM status of the AC request or switch? If the value "yes" or "on" is shown, check the status of the compressor clutch relay and fan status, they all should turn on when the AC request is made to the PCM.....
If not, is there any value in the datalist that would prevent the PCM from allowing the AC to operate?
If nothing unusual is seen....or no AC request is seen in the PCM,
Then I'd turn to the HVAC panel to put it in self diag mode, see if it shows any faults/codes/problems.
I think you may want a good service manual for this, or search. IDK if the hybrid system diag is vastly different from the normal car or not.

Re: 2008 Civic Hybrid Air Conditioning
Same problem here with my 2007 HCH AC
- AC freon was getting a little low (I shouldn't have ignored it) - now it finally stopped altogether
- both fans won't run
- clutch will not engage without jumping relay connectors
anyone learn anything?
