1998 BH5 GTB - Can't adjust heater temperature

[Captain Salty]

Hi,

 

Seeking help with the heater / climate control system in my '98 Legacy. The dial to adjust the temperature just turns indefinitely and the temperature doesn't move. Obvious fix is to source and purchase a replacement unit but I thought I'd ask here in case there is an easy fix.

 

Thanks

I have a 98 Legacy. There is no dial to adjust heater /climate control temp, just a slide lever, with cold being on the far left, hot on the far right.

 

Oh, I see, you are from NZ, maybe the heater control system is different from cars in the USA.

We never got a climate head like that in the US as far as I know, but we have plenty of members from NZ, hopefully they'll be able to chime in with some tips.

Thanks, it looks like this

It's either a potentiometer and the center post has broken that connects the knob to the pot.

Or it could be an LED rotary encoder type knob and the LED has stopped working or is very dirty.

How adventuresome are you when it comes to taking things apart?

Thanks. Yip happy to pull apart and have a look, just didn't know what to look for.
