Shop just called and it threw two codes -
Thermostat
Brake Switch/ABS
I told them to clear the codes and go ahead with the cooling system drain/flush and refill, as maybe that will help the thermostat, but the thermostat is brand new so I'm not sure why it might be throwing a code.
As for the brake switch/ABS, i'm at a loss on that one
no idea what it could be or how to fix it. Any idea from you experts?!
