Re: A/C not working on high speed fan setting
Ok. before I start drinking again I hope someone can figure my problem out. My fan never worked on high but i'm not a real fan of AC and our cabs are small so never really needed it. With Covid 19 and self isolation a man has to do something so I thought that I would get into solving the problem. Fan works on low and medium, nothing on high. I did the 12 volt test at the relay and have power there. Here is the problem, when I remove the ground wire from the relay, the fan motor works on high. Now low speed is low and medium seems to be medium but when I switch to high the motor comes on but the rpms drop a bit from the medium position. I've read many articles about making sure the ground is in place properly but none ever say take the ground off. Hope someone has the smarts to figure this out for me. Dam Covid19 anyway. Solve my problem so we can both have a good day. Stay safe eh. Ron
