I got a bid of about $2300 to replace the dash a/c compressor in my Bounder(Freightliner) 39' Turbo Diesel so with a little knowledge and help I needed to do it myself. I had no problems replacing the compressor but I still do not have power to the clutch. Clutch is working when I jump it with 12V. I was told 3.8 lbs of 134A was correct and I flushed, vacumn pumped and put that in. Also the snowflake on the dash control will not light blue. Fan works fine. Does anyone have an knowledge of this rig. Such as does it have a low flow switch, where is the condensor, etc. Where would the fuse for clutch be. Any help would be appreciated. Joe B.

Welcome to iRV2.
Any idea what the brand name of your A/C system is , Evans , Acme & Denso are common, my brand was cast in the plastic housing near the heater hoses at the front of the coach.

If it has the Evans system go to the QT's 1 & 2 LINK and all the info on Evans is there.

Thanks everyone for the help. I believe it is Tempco Evans, but I can say the old compressor said Acme. And some of the paperwork that come with it from the factory is from Denso. My main problem is I cannot find low pressure switch or even condensor. Thanks Joe B.

It is manufactured by Denso, see attached for the parts list. If you need the troubleshooting guide let me know, I have it also.

Pull the connector off of the low pressure cutoff switch, and jumper it with a piece of wire. This will pass the 12 volts to the compressor and allow it to turn on. Once you have a few ounces of freon in the system, you can pull the jumper and reinstall the connector. The low pressure cut off switch is usually located near the receiver drier.

Don't know how many changes Freightliner made over the years , but my condenser is mounted ahead of the front axle , between the sway bar links , behind the gen set. Best access is with the gen set out.
Low pressure switch I'll check my wiring diagrams , but it may be hidden on the connector on the back of the receiver/dryer. Mine is beside the gen set about 2' from the firewall A/C connections . BB.
