W209 Heater controls - help please!

[aileinomuireasain]

Hi All,

Firstly, apologies if this has already been discussed. I found some discussions about a similar issue in W203s and another mentioning duo valves, which apparently the W209 (CLK) doesn't have so I am well and truly going mad.

When I turn the temperature on my climate panel to 18 degrees the air is luke warm. When I turn it to 26 the air is hot. I tried depressing recirc and windscreen demist buttons simultaneously and after a little while of the lights blinking, the recirc button now stays illuminated.

I am hoping to sell the car on to change to a W212 E-Class coupe but the purchaser essentially wants to know if it is a big problem to fix. The AC needs to be regassed but I believe I'm correct in assuming the AC is a sealed unit and should not affect the operation of the heating controls.

Any help would be greatly appreciated.

Kind regards,

Alan

This is normally a heater flap problem, take a look in the DIY section and a post by me on re setting the flaps on a 203

Hi Malcolm,

Thanks for directing me to your post, assuming I have the right one - "203 reset of blowers and actuators"

It seems I have an older climate control module though - mine has the two rotary knobs.

I have tried the reset function but the recirc led remains lit.

Have I followed it correctly? Apologies if I should be commenting at the bottom of your post.

The 203 and 209 are usually the same, my problem is that I am not that clued up on these cars. STAR would give the info that is required to see what is wrong. If it needs to be re gassed, this will keep the lamp on.
