heater value
 

Hello Shop Forum: First time user.. I have a 98 ML320. I think the heater value is fixed in the open mode. It's letting heat inside the car. (HELP TO LOCATE PART: HEATER VALUE)

What you are asking about is a "heater valve"! The ML's Don't have one at all they use a blend air door to change from heat to A/C...do you hear any clicking noises from behind the dash area?

air temperature control
 

A have that strange ticking noise coming from behind the air temperatuire control switch on my dashboard.

The ticking stops depending on where the air temperature control is set. At full cool the ticking is present, at the 12 o'clock position the clicking stops.

The temperature of the air coming out of the vents does change with the position of the control.

Where might the ticking be coming from and how would I go about fixing it.

Thanks.
