I have a 92 Civic DX manual transmission. Is there only one ECU or is there a seperate one for the A/C? It looks like I need one for due to an A/C problem and wanted to buy it myself but wasn't certain if the one for the car controls everything or if the A/C has a seperate one. Also, if anyone knows the part number I would appreciate it.

Thanks

What's the A/C problem anyway? Maybe someone here can help you.

 

there is only one ECU. the A/C is controlled partially by the main ECU.

list the symptoms, many on here are good at solving problems like this.
