dlappleton5 Posted August 29, 2022 Share Posted August 29, 2022 While removing the old module realized the plug is burned up. Can anyone identify what this part is that fits behind the module? It needs to be replaced. Quote Link to comment Share on other sites More sharing options...
Joey Mack Posted August 30, 2022 Share Posted August 30, 2022 looks like the socket behind a CH/CX/ CV... model,,, fans speed switch.. It would be nice if you posted much more info about the truck,,, year/ model/ eng./ tranny/ just for the heck of it... by the way, that harness is easy to fix, and Mack still sell's it, but you have to take the whole thing out of the HVAC, cores/system... If you put di-electric grease on the terminals of the new one when you plug it in it will help, a bit.. that melted socket is also replaceable if you know how to release the female blade connectors, then re-set the locking tab's .... it's easy... jojo 1 1 Quote Link to comment Share on other sites More sharing options...

Joey Mack Posted August 30, 2022 Share Posted August 30, 2022 put some dielectric grease in the terminals... jojo 1 Quote Link to comment Share on other sites More sharing options...
dlappleton5 Posted September 6, 2022 Author Share Posted September 6, 2022 @Joey Mackthanks for the advice on the grease. Hubby put all together, the new harness with a new A/C control panel. Of course our luck, No AC, the fan does however come on now with a light blinking at the control panel. Any recommendations? Quote Link to comment Share on other sites More sharing options...
Joey Mack Posted September 6, 2022 Share Posted September 6, 2022 was the thermostat hooked back up in the evap core? check for power at the plug on the receiver dryer and a/c compressor.. keep it simple... oh yeah, is there at least 50 PSI of freon in the system? jojo Quote Link to comment Share on other sites More sharing options...
