Need help diagnose problem with A/C clutch

Couple of weeks ago, my fiancé’s 01 Civic 2D A/C started to crap out. We took to a shop and they refilled the system to see if it would fix anything, that cost us $140 and it seemed to have fixed the problem. A day later, the A/C started working intermittently and then stopped all together. Before we took it back to the shop, I started to do some digging on the internet to check for some common A/C problems. What I found was that the AC clutch was not engaging.

So I figured it would be a simple clutch replacement job and took it back to the shop to verify. They confirmed the clutch was the issue and that it would cost $700 to replace the compressor (even though it was working), clutch, evacuate and refill. Not ready to drop $700 just yet, we're recent college graduates so money is a bit tight right now as we settle down, so we decided to just ride it out and wait until we have some $$ we can allocate.

In the meantime, I continued to do some research. I checked the 1 (hood) & 14 (dash) fuses, good; swapped the relays (used horn relay to swap), nothing turned on; jumped 1 & 2 (blu/red) on the AC clutch relay, and BAM, heard the clutch engage. Disconnected the jump wire, turned the car on and the AC was spitting out ice cubes. Though that it was fixed and let her drive a couple of days. Yesterday, after coming back from the gym, my fiance said that the AC did not work on the way to the gym but did on the way back. Checked this morning, seems to be working. I'm assuming it's going to get worse until, again, it stops altogether.

Any ideas? Am I hosed or can we try something else that doesn't require extensive mechanic skills or crazy tools? I really would like to save the $700 for something else.

I've never messed with A/C myself but it sounds like you have a mechanical aptitude and could easily avoid paying a mechanic to do the work. Find the parts you need and go to town! Check local salvage yards for A/C parts on a low mileage Civic or check Amazon/various auto parts stores for what you need.

DO IT! :thumbs up

More information is needed to determine whether you have an electrical or mechanical problem.


When the A/C won't blow cold after pressing the A/C button:

(1) Does the A/C condenser fan fail to run?

or

(2) Does the A/C compressor clutch fail to engage?

or

(3) Both (1) and (2).




Finally, have you tried pulling trouble codes from the climate control panel?

The condenser fan runs, however, clutch failed to engage. It wasn't until I pulled out the clutch relay and jumped 1 & 2 (blu/red), did I hear the click of the clutch engaging; when I removed the jump wire, re-installed the relay, and started the car, the clutch engaged and AC was blowing cold air. Until yesterday, when it started to work intermittently once again.

For the codes, how do I pull those? I was actually planning on ordering a OBD2/Bluetooth dongle for my Accord to work with Torque on Android, would that be able to pull any relevant information?

If there are no heater control panel codes, then use a code reader to check for CEL codes.

If there are no CEL codes, then make the measurements indicated in the diagrams. There's no need to remove the compressor to do the tests.

Ok, she's out of town until tomorrow, but as soon as she's back I'll run the codes and check the measurements. I actually just got off the phone with her and the AC is still working, so we will see how things go over the next 24 hours.
