Hi all,

Today I was working on my 1996 Honda Civic DX and while testing my AC system, I saw a spark in the fuse box while jumping the condensor fan relay and then my radiator fan stopped working and the green and amber lights on my HVAC panel stopped working. Was wondering about any suggestions and where exactly the radiator fan fuse is as I have been scouring through the owners manual and online to find out which fuses to check. Thanks!

 

Ahh, I feel stupid now, just found the fuse in the diagram - #57. The fuse looks alright, but the fan is still not turning on and the Heater control panel is still not showing the green/amber lights. It is showing the backlight bulbs.

 

id jump that fan to make sure it still works. A buddy of mine while hooking up an amp took out the fan motor (among other things)

now he just pays me to work on his car...lol for good reason

 

as for hvac panel....

quick search here will answer practically anything you can dream of.

 

7.5A dash fuse 17

 

Alright, looks like I've got the radiator fan and the panel working correctly (I counted the fuses wrong haha, learned not to count the spare fuse under the dash). Now the A/C button turns green, but the condensor fan and the compressor do not start. I've tested the relays and they are working, I jumped the 2/1, 3/1 on both relays and both start their respective circuits. Any ideas as to this problem? Thanks for the help (and putting up with my late night stupidity)!

 

20A hood fuse 56

 

Okay, just checked the fuse it was okay but replaced just in case, AC compressor still not turning on.

 

Fan running?

 

Radiator fan is running, the condensor fan is not.

 

Unplug the a/c thermostat and ground the blu/wht wire in the plug. Does the fan and clutch now work?

 

Which connector is for the a/c thermostat? The wires on the right side of the condensor?

 

Evaporator - behind glove box.

 

Yes grounding the wire turns everything on!

 

Reconnect the thermostat and then unplug the connector at the rear of the heater control panel. You'll see a Blu/Red wire in the connector. Ground it and then turn the key to ON(II). Does the A/C fan turn on (no need to press A/C button)?

 

Mine only has twelve connections but after grounding all of them, only the blower motor and the ac light came on. I can post a pic if it helps.

 

It's probably the wrong connector. It should have 14 wires. Did you find a Blu/Red wire in the connector? Post a picture.

 

Okay just a sec it is a brown connector does that sound right?

EDIT:Never mind, I just found the green connector behind the temperature slider, will ground wire and post results.

 

Okay grounded the red/blue wire and turned on, no activity in a/c.

 

Your test results indicate that the heater control panel is bad.

 

Will I need to replace the entire climate control module?

 

Yes. You can buy either a new one or used one from a 96-98 Civic.

 

Thanks very much! I will post my results as soon as I get a new one installed.

 

Is this^ a typo? And are you saying here^ that the condenser fan ran when you grounded the Blu/Red wire?

 

Yeah, sorry it was the blu/red wire. When I grounded that wire, I did not see the condensor fan start.
