I'm driving a 2007 honda civic hybrid. My AC compressor runs on belt and electric. Currently the AC only runs on belt and when the autostop kicks in the compressor does not run electronically(used to hear some sound from the engine when the compressor runs electronically). Is the compressor spoiled or some fuse or relay burned?

check the switch continuety /a short somwhere?

I have a 2006 Honda Civic Hybrid and have had hell with it. I have also learnt much about it too.

One thing bad about the HCH2, is that the 12V battery controls the electronics, and the Hybrid battery charges the 12V battery. However the 12V battery is not charged all the time, and cannot be charged when the IMA is usually being used, and in different scenarios. (Buy a Electronic volt meter which plugs into the 12V adapter $14 Walmart))

It is possible that the 12V battery is being drained while driving and caused a voltage drop which can cause your problem. In your case, I would change the 12V battery anyway as they do not last long on Hybrids. (You may have to get Honda to trip the IMA warning lights.) In my case, changing the 12v battery helped the hybrid battery as it was the electronics reporting the charge level wrong.

Depending where you live, you will have a minimum 80,000 mile warranty on the hybrid battery.

Hello, You have two switches which work off the pressure of the Freon. Both of these switches cut off the power to the compressor. One is for HIGH pressure and the other is for LOW pressure. Check for power at the compressor clutch connector harness while the controls are set and the engine is running. You may have power and a bad clutch.

When you say that the Freon pressure is good, does that mean the pressure is within the proper range? Too much Freon will make the HIGH switch cut off power and too little will make the LOW pressure switch cut off power.

The ideal amount(ozs) of Freon is what is recommended by the Manufactuer and it will provide a moderate amount of pressure of about 35psi-40psi. You can borrow pressure gauges, called Manifold gauges to measure your system at autoparts stores with loaner programs.

The low pressure side of the system is the one you use to induce the Freon to go into an empty system. You can bypass this switch by taking off the connector and putting a "U" shaped jumper into the harness and the compressor clutch should get power to LOCK up all of the time.

You can take off the switch connector at the compressor clutch and then check for power when bypassing the HIGH pressure switch if the LOW pressure switch does not make the system get power. Only, really only bypass the HIGH pressure switch with the clutch connector disconnected. The HIGH switch is there to prevent damage to all of the components from seals to lines to every piece of Freon hardware in the car. Bypassing with the A/C clutch disconnected will allow you to know if power is getting to the compressor clutch.

Finally, you can get FREE wiring and fusebox diagrams through Autozone.com. Just sign and register to their site and then you can print the documents for yourself.

Good luck with this repair and I hope my solution helps you.
