So I felt like it was time to cut the heat on in the old truck. I immediately regretted it because I turned the knob too hard, and it busted. It just kept spinning without doing anything in terms of heat/cold adjustment. I did it while I was at work, so I had to wait to open it up and take a look at it. Long story short, my blend door wasn’t working correctly; it still isn’t. For those that don’t know what a blend door is. Don’t quote me on this, but it basically acts as a blocker to the outside air that blows into your vehicle when you activate certain settings on the climate control. For example, when you want the heat on, you turn the knob to warm, you can’t have all this cold air coming in from the outside blowing in the cabin. I feel that explanation was terrible. Here’s a clue as to how to know if you have an issue. The a/c or heat is off and you have a strong breeze still blowing through the cabin via the vents.
That explanation wasn’t very good, but I hope you get the gist of what I had to fix. I had to fix the knob that prevents or at least cuts down on that. My thing was, I don’t really care if I have heat, but I want the a/c to work at all costs. This isn’t my daily truck, and it lives in a garage. The pulley was stuck to the heat/warm position, and it wouldn’t stay in the cold position.
The fix: there isn’t a fix that I know how to do, so I had to seal it back up. Not before I broke the pulley system that controls the heat/cold temperature, which isn’t ideal. I was able to put some JbWeld, so it still gave me a way to control the temp. I also realized that I don’t even think I have heat…lol Seriously, as long as the a/c works, I’m not complaining. I don’t drive old blue that much, and I’m for sure not driving in cold weather out here in Arizona… I feel like I didn’t accomplish much; however, I was able to put in LED lights, which brightened things up a bit. Taking the a/c climate unit off was easy, and that led me to take off the dash bezel, which was a little more difficult. I couldn’t get it all the way off, but it’s another project for another day…
