430 Ticking sound, heater now not working, video

What in the world!? I've never heard climate controls in ANY car makes that much noise. Even as you turn the recirculation on and off... crazy how it sounds like an engine exhaust note. Mine are all completely quiet.

 

The ticking noise sounds like a relay chattering, the other noise is like a motor running ?

 

Look at plate 139 evap unit, it shows a recirc motor so this might have become disengaged - that would explain the noise when you push the recirc button. It also shows 4 Bahler actuators which might be the clicking if its not a relay

 

Sounds like a disengaged lever.

Take a look behind the stereo system head unit on passenger side. You will see a lever the pulls the vent director flap open or close.
That may have disengaged.

Nice work Daryl. I had to google the TGK valve, Appears this is just an expansion valve manufactured by TGK?

 

Is this just controlling the hot water flow to the heater then ? Its not in the chiller system from what i can see

 

Correct. Although AC vent flap linkages could cause the clicking noises, I did think it strange that they would stop heating (the heat should come out somewhere, no?)

 

about 1 liter or 2 will come out.
been there done that.

 

This just happened to my car, 2008 scud with 15,000 miles. Took the car for the last drive before putting it away for the winter and I could hear the ticking sound somewhere in the dash area. I put the car away and planned on dealing with this in the spring. This thread came up shortly after I put it away and I finally had the time to remove the fuse and turn the key as instructed above. This worked, I tried turning the key several times and no more clicks, thanks Daryl.

 

Daryl - thank you for posting this thread! Same exact issue started with my 07 F430 about six months ago! I was like...what the heck is that ticking noise behind the stereo/heater console - sounded like a stuck relay switch or plastic motor. However, mine started after I had to recharge the battery as it was completely dead from sitting for 4 weeks. After putting car on the tender to recharge battery overnight, I started the next morning, and boom...loud ticking noise which I had never heard before. Lately, the ticking has become intermittent and not ticking at each start-up. Heater/AC have been working fine. It's become more of a nuisance, but definitely was to get this resolved and therefore appreciate the potential fix with pulling the fuse. I will try it.
Kind regards.

 

I write a procure document for this. See attached.

Sorry to bump up an older thread. But I just got this ticking sound behind the dash, I wanted to try pulling the fuse. But which fuse exactly is it? and where is it located? Thanks

 

The TGK (hot water) valve is powered by the HVAC ECU. The HVAC ECU is provided with power from two fuses. One is the maxi fuse #3 near the battery (probably a lesser known one, so not the one pulled). The other is PSF13 ("+15" Air Conditioning system,"+15" recycle pump) behind the left hand seat.

+15 means that the fuse is powered by the ignition, so I'm not sure why turning the ignition off wouldn't do the same thing.

Maybe @BlacktopRacing can clarify?
