AC Project 1152

[abfisher1798]

I’m converting a 1152 to a four-man configuration with a hard top. It has a factory AC for the driver and passenger. I have a RedDot evaporator on hand. I am thinking about putting that in the back, between the seats for the rear passengers. What would that look like?

I have an extra fender condenser for the left side that could be incorporated, along with many of the OEM AC hoses. I think I can add the condenser, splice it in with the new hoses and branch the RedDot (somehow) off the hoses that are designed for the factory rear unit. What could go wrong?

I live in the Southern California desert. Our average summertime temps hit 120 plus!

It seems like an easy deal, but that is never the case!

I definitely wouldn’t, I find my M1152 converted to M1165 sufficiently cools with just the front evaporator. If you did want to do it, install the OEM equipment

I also converted my M1152A1 to a four man configuration and was thinking about increasing the AC capacity. Are you saying you find the 2 man AC system to be sufficient? Also, exactly what would we need to increase to 4 man capacity?

Before you decide to spend a bunch of time and money on expanding an m1152’s AC to 4 man...convert to 4 man and see how badly you think you need it. Even a 4 man setup is just OK, it’s not going to freeze you out of the cab.
I have both 2 and 4 man AC setups...

Very good advice. My truck only has two toggle switches at the bottom to control heat and ac. I want to replace the faceplate but can't find one with just the two toggles at the bottom. Does anyone know this part # or where to get it? Thanks.
