So I started having issues with my truck ever since the AC went out in October, I took it in to get fixed I was told it needed charged, this did not fix my problem at all, then I noticed my engine will continue to run for 20 minutes after the truck is shut off, I took it again and was told nothings wrong with it. My check engine light comes on and I’m still told that nothings wrong with the truck. Clearly there’s something with my truck and I’m not really sure why the mechanic won’t look more into it.
