HVAC sound, when to fix, when to live with it

[JonMN]

Compared to most of the other problems I have seen here, this is pretty trivial. But hey, it's rainy here today and killing a little time on the forum. By the way, we are really happy with our Gladiator!!

Since new last year, there has been a ticking/clicking noise as the HVAC system settles down. Sounds like mostly in the dash area. Once the temp is arrived at and the system settles down the clicks are pretty rare. The dealer did the first step of replacing the Driver's blend door actuator, but that did not help. Looking through the service manual, there are multiple doors and actuators to direct the air flow. The next step would require full removal of the dash. I did watch a video on this, and it does not look like a fun project.

Questions for the forum:
Is a little clicking common for Jeep HVAC? Does yours? If my memory is correct, the other one I test drove did the same.

Would you go thru dash removal to try to fix it? I really wonder if they could remove/replace all the components without some damage. I have a secondary thought that they might replace all the parts and it would still click.

An alternative fix is to just put on Robin Trower and/or Stevie Ray Vaughn and crank it up a bit . . . Hey, it is a Jeep after all!

Mine is always clicking until it gets temp under control. Everything appears to work fine though, so I'm not wasting my time at the dealer for it (in addition to the hood corrosion that needs fixing, and the TSB for the multiple misfire....I mean maybe it could be a 'hey while you're in there...').

I personally would remove the dash no problem. It's the trusting other people I don't always like, lol.

Hey, thanks for the reply. I was just wondering if I was the only one with clicking.

I get the clicks too when it starts up. Sounds like maybe a blend door opening. I was trying to remember if it’s always done this or not but can’t seem to recall when it started. Anyway, it’s working fine so I’m not doing anything about it. Last thing I want is my dash to be torn apart.

I’ll probably mention it on a service ticket if I ever have to bring her in to the dealer just to get it on record.

Mine has had the clicking since day 1 as well.

This sound is from the HVAC Temperature Valve Actuator Mopar part 68301847AA.

It's behind the glove box. That third screw in the rear is a b1tch to get out. I left it out when replaced.

I had the clicking sound for months until I replaced this part. Pretty common failure point on Chrysler vehicles. Cost me $20 on ebay with free shipping.

Thanks all for the replies. Think I came up with the perfect solution: Time to order a set of tube doors
