Heat blows from defrost only
Hi all,
First time post and new guy. I had this problem and did some research online. About 95% said the actuator was bad and needed to be replaced. Its kind of a pain to replace the actuator and costs about $50 or so. Saw the following online and tried it. Low and behold it worked. It seems the actuators get stuck sometimes when the battery is disconnected and they go some kind of reset or recalibration. So, all of a sudden you find it starts acting funny or just stays in one vent and wont change. I had this very same problem, and this fixed it.
I had a similar issue. Air would only blow out of defrost vents after I replaced my battery. But this worked for me:
1) Unplug HVAC fuse for 10-30 seconds
2) Start truck
3) A/C comes out defrost - wait about 10 to 15 secs. If not, cycle the distribution **** ( for lack of a better term), the one that selects which vent it comes out of. I had to do this before it would cycle.
4) A/C then starts coming out the floor vents for about 5 seconds
5) A/C then starts coming out the dash vents.
6) While the A/C is coming out the dash vents, turn A/C OFF (otherwise it cycles back to defrost for good).
7) Turn truck OFF
8) Restart truck and it should work fine
I did this and everything works fine now. Dont know for how long, but its better than fighting with the actuator, panels and pitching out $50. Good luck.

Dear Stormyj,
Thank you for your post. Just a question: What did you do with the fuse? You said,
1) unplug HVAC fuse for 10-30 Seconds.
2) Start the truck
My question: Shall I put back the HVAC fuse after 10-30 seconds before starting the truck OR start without putting the fuse? In this case, when should I put the fuse back?
I will appreciate any elaboration on this, PLEASE HELP!!

HVAC Fuse
This is great advice and I want to try it, but I'm feeling pretty dumb right now...I cannot find the HVAC fuse, where the heck is it???
