Honda NSX NA1 Air Conditioner Malfunction Repair

Since the beginning of this year, the air conditioner has become unwell, so I repaired it.

First, replace the air conditioner control unit. I ordered one genuine part, “37735-PR7-A01”. The photo is an old one after replacement.

The installation location is a black box next to the main relay on the rear of the driver’s seat. It is fastened with two 10mm screws and is a coupler on, so it can be easily replaced. However, although the screw below is not shown in the photo, the gap is so narrow that it is difficult to detach it without removing the interior. It’s easy to get with tools. After replacing this, the air conditioner compressor started to work well and the cool breeze came out.

Just in case, I also exchanged these two relays. There are two “39794-SL0-J01”

I replaced the two inside the red circle in the innermost case in the bonnet. One in the front is an AC relay, the other in the back is a condenser fan relay. It has claws, so it’s difficult to remove, but when inserting it is easy because you only push it in. It is done!
