Clicking from dash, no COLD air

[fauskie]

I saw a lot of other members had issues with their heat being stuck in cold position but I didn't find any posts similar to mine.

About 3 months ago, felt resistance in temp selector dial and forced it over to full heat. Felt it "break" loose and was able to get hot air.

Last month, I need to start using the a/c and when I change dial to coldest setting I hear clicking from dash (sounds like it's behind and above the cd player/deck). I need to move the dial a few notches towards heat to get it to stop. But by doing so, the air isn't all that cold and my a/c isn't nearly as effective.

What should I look for behind the dash? I read one post about a plastic piece by the gas pedal but that was for an issue where hot air wasn't working.

The clicking is constant whether in recirculate mode or not and I have not noticed any leaking on passenger side floor.....

Push the recirculation button it should go away

Is it just me, or does it sound like you have two different issues? Just my opinion, but I think, maybe your knob is not turning all the way to the left or is not making enough contact to the plastic behind the knob to make it go all the way to cold.

Another suggestion, that might be totally wrong, but might be worth considering, is to see if your freon levels are good. Although this might be unrelated, the fact that you are not getting cold air, might just mean that you have low freon and need a recharge.

The clicking from the dash is usually because the heater control actuator is gone, there are a lot of threads on here which tells you what needs to be changed. I'm thinking the clicking and the cold air might not really be related.

Just my two cents.

clicking is constant (when knob turned to either full cold or full hot) whether in recirc mode or not

I thought about the A/C system possibly needing a recharge after I posted last night. I'm going to check that after work to see if that is also a contributor to the lack of cold air.

Would the clicking from the heater control actuator also occur when the temp knob is switched to coldest level?

Thx for your input, I'll try to rule out/confirm the freon & the plastic knob not making contact when I get out of work tonight.

Yes, it's basically when the heater control actuator that turns on/off the heat cannot engage, because the gear wheel inside the actuator has worn out with constant use. So it keeps trying to engage/disengage, but doesn't actually. I would go out on a limb and say that it's probably trying to disengage when you turn it to cold.

Get a new hvac and cable, I had the same issue, the cable was bent and wouldn't move freely, and the gear was striped behind the knob,

The actuator is toast and my ac needed 2 cans of r134a.
Still contemplating on if I wanna replace actuator. I had dash off and was trying to push the arm/lever to full cold position but it still clicks/knocks like crazy. The air is still nice and cold when I move the temp position a small click towards heat so I may just deal with it.
Thx for all the feedback & help!

Its a pain to replace if you have big hands lol.
I replaced mine a year ago and it was deff worth it.
