1998 Fleetwood Discovery A/C Compressor Fuse wire

I have a 98' Fleetwood Discovery on a Freightliner Chassis w/5.9 Cummins.

Took it in to shop to 'fix' Dash AC and the shop added 3lbs of freon and said it was blowing cold 48degrees at dash. I picked up next day and it was not working. Took it back and they now say there is no power on the single black wire to the compressor. They cannot find any blown fuses. I paid $1200 for a non working repair and they have spent 5hrs of searching for the bad wire (all this makes no sense as to why it stopped working)

Anyone with any info or help how to locate the Spare Fuses for the AC compressor wire #1156 (per Freightliner chassis wire schematic-hoping it's even the correct schematic) would be SUPER helpful as we are leaving in 1 week for a vacation to Florida

Please pass on for any help! I run a print shop and will 'donate' free printing of anything you need for the solution!!!

Thank you So much!

Hi. I searched for days also looking for the compressor fuse on my 2008 Freightliner. I can't say for sure that the Denso service manual attached will help as I don't know what years it covers. I can tell you that under "Component Locations and Positions" in the manual, there are drawings showing locations of parts...including the fuse. I found mine taped up into the existing harness. It was difficult to see. It's a glass cartridge fuse. Best of luck.

Ok , I know that Freightliner wiring underwent a major change Jan 4, 1999; but maybe the spot where Newmar , tied into the Freightliner wiring for the Evans power feed to the engine mounted compressor will be close to the same ; as where the connection is on my Feb 1999 chassis .

Above the gen set ; blue wire is Evans , white is Freightliner ( no fuse beyond this point) , multiple connector above , is for the right side head light and signals .
Third page of the pdf , shows how Evans would have liked to see wiring done .

Important question is ; Is your dash HVAC system Evans/Tempcon ?

Power flow to the compressor , on Evans system , goes through the temp sensor , then the low pressure switch before getting to the Freightliner wiring .

Follow skip426's guidance for the fuse. I think he is spot on about the power lead for your Denso HVAC.

Hi Skip, Checking out your post, you have quite a bit of knowledge when it comes to dash ac. I have 2005 Fleetwood Expedition Cat C7 with a Denso AC Unit. I have no power to the compressor. I was able to put 12v to the compressor clutch and everything works fine. I cannot find any fuses or relays with issues. The only area I have not accessed is inside the HVAC unit where I believe the pressure switch is located. Any assistance would be greatly appreciated. Also should note that my dash control snowflake, the light is on so just not sure where to go from here. Thanks, Gary

Gary ; I haven't been hands on with a Denso unit .

I have read a couple of posts from members who have changed the pressure switch , that I'll try and track down , maybe info in this pdf will help.

dash ac

Thanks for the info, Skip. I have been looking at that. After reviewing it again, I see that there is a fusable link that comes out of the condenser relay wiring. Could that cause the system to not function? When I put 12v to the clutch, the system functions as it should and the condenser fan also runs.

on my 2008 Discovery there are two Fuse Holder under the dash. One is near the Dash Air Control Module it's a white holder easy to find. The Second one also white is taped to a bundle of wires if you have this set up it's behind the large fuse box
