I bought this truck roughly a year ago and it's recently been giving me some issues. No check engine light but starts getting warm when sitting still when driving is fine it has a new radiator and cap put in when bought and the system was flushed about 50 times due to the stop leak I could see in it. My first thought is electric fan clutch wanting some other opinions. This issue presented itself at the same time as my ac issue. Was on a trip out of town and the ac just stopped blowing cold seen the clutch wasn't engaged hooked up guages and found it was overcharged. I corrected the charge issue and clutch works as expected but now I don't have cold or even cool air crazy thing is it was working well and blowing very cold when it was way over charged.... thoughts?
