In my effort to remove a cracked and leaking heater matrix I managed to break the plastic control piece that comes out of the potentiometer that attaches to the top center lever on the climate control which I believe is: RND581 POTENTIOMETER - A/C. The RN website says they are NLM and to contact you. Do anyone have a good spare?

Am I remembering the advice correctly that one should go ahead and replace the blower motor at the same time of the heater matrix?

I found all sorts of crap in and around the matrix including a build up of the foam material on the flaps/louvers within the housing. Has anyone replaced the foam? Doesn't look like its possible but the foam and it looks to continue to fall off. Should I scrub the remaining foam off so it doesn't continue to fall off and blow into the rover.

Thanks,

Mark
