I have a 97 Accord EX Wagon Auto. The A/C stopped working. The dash A/C button would light up and the interior fans worked but the air never got cold. When checking the engine bay fuse box the 15A condenser fan fuse was blown. From my understanding this fuse provides power to both the condenser fan and the compressor clutch.
I found the below linked thread from the FAQ useful. DIY #3, Step 4 was relevant to my issue. A/C Troubleshooting
My Diagnostic
I'm sure there is a diagnostic you can do with a voltmeter but I had a $10 box of hundred some fuses so I wasn't worried about wasting them. I turned the car and engine off when connecting and disconnecting all parts to avoid potential damage. Also I should have checked to see if the condenser fan blades spun freely, it would have saved time.
To check what my problem was I unbolted the two relays at the front driver's side of the radiator. The one closest to the engine is the condenser fan relay and the one closest to the radiator is the A/C clutch relay.
To unplug the relays you don't need to peel up the protective boot. It will probably tear if you do. Just squeeze around the center of it until you are able to pull the plug loose. I unplugged the condenser fan relay and replaced the fuse to see if it blew again. It didn't.
Next I unplugged the A/C clutch relay and plugged in the condenser fan relay. The fuse blew at this point.
I then plugged the connector for the condenser fan relay plug into the A/C clutch relay, replaced the 15A fuse, and it blew again.
The common problem here appears to be the condenser fan.
*note* I would have know this was the issue without any work if I had merely tried to rotate the fan by hand. It creaked and popped and resisted all attempts at rotation. I noticed this when removing the part.
Condenser Fan Replacement
So remove the two 10mm bolts holding the top of the condenser fan in place. Loosen but there is no need to remove the one 10mm bolt holding the lower side of the fan onto the radiator. There is a fork on the bottom of the fan that rests on this bolt. Unplug the fan and undock the connector that goes to the compressor. My $65-$25 in coupons=$40 Advance Auto Dorman replacement fan. Install is reverse of removal. No need to torque things like crazy just snug them up.
I replaced the fuse one last time and now my A/C is working great again.
