Have read several posts on here with similar problems to mine but not identical. Current problem is on drivers side. I have had this EXACT same problem before on the passenger side and dealer fixed it. Am now out of warranty so trying to fix it myself. Let me explain my problem. Start truck up and heat comes in just fine for about 10-15 minutes then starts blowing cold air out of driver side. Change setting with no changes to actual air blowing out. After a while it will start blowing hot air again. Repeat over and over. Same deal when running AC. Will blow cold air for a while then start blowing piping hot air after a while. Help please!
