OK, I think I know what I need to do (resolder A/C contacts), but before I take everything apart, I wanna know if theres anything else I should look for/diagnose. This happened on Saturday, I got in my car after leaving work, and it immediately started blowing hot. You can definitely feel its the heater thats on. I have an aftermarket radio installed, A/C worked fine when I installed it. Any suggestions??

 

Is the A/C clutch engaging?
