I have a 2010 ram, having issue with the heat it’s only blow hot air on passenger side. I do hear clicking sound comming from behind what seems like center of dash. I also recently installed a new theromostat, I did crack open the bleeder a little to let air out, ran it with cap off topped it off and I still can’t get the temp to get near middle bar even after I put cap back on and let idle. Any help with Both issue would help thanks.
