What have you just discovered that you should have found out years ago?

MissMoppet · 2nd November 2019, 15:14

Confession time.
For 6 years I've run my R75 Tourer with the AUTO button on as the handbook says that is the simplest way, till I've recently learned that the ECON button should - possibly - be labled AIRCON. I will now only use it in the summer. That could possibly be why I had to have the compressor changed last month. (A rare event I believe).
But how about you?

I quickly found out that having the econ button pressed and displayed disengages the A/C compressor. I get the whooshing noise and it sounds strained, so it will remain off until Artic can work his magic next year and get my fan working.

I do have a hand book with my ZT, but i'm a more of a "What does this button do?" type of bloke!

come winter and misted windows you will want to turn the aircon on as it helps demist.

ECON button is NOT aircon. (I may have misread your post though). In wet damp weather, I use the aircon on, by switching OFF the ECON, and switching to feet and windscreen, at my desired temp, with a low fan speed. This will help to prevent the windows steaming up. With ECON on, which I do use frequently (I drive with the window cracked often) the windows can and do steam up, but still use the same settings as with aircon.

I generally use the econ button as my A/C compressor is noisy and I would rather not have to change it until absolutely necessary.
(I take it changing the compressor on a 190 is bumper off and rad out?)

Just out of interest why does the aircon help the demist?
I thought it only provided cooler than ambient air.

Things I should have realised years ago?

Aircon air is both drier and cooler and so as the cabin is de-humidified, the drier air accelerates evaporation of the small droplets that mist up the glass. I generally leave my climate control on auto and find it keeps the windscreen and side windows free of condensation regardless of how damp it is outside.

I can't remember ever taking my aircon off auto since I bought it in February 2004. I know it has been occasionally when in for service, but it has gone straight back on when collected.

I usually run about with my Aircon off - apart from the summer & giving it a run a couple of times a week to keep things in working order. My compressor whines so I'd like to prolong it's life before I have to spend on that.

Concerning though that so many members say their cars will most up without the aircon on. I have no such issues in any weather conditions. Time to check the old carpets?

Always(well nearly) have A/C on-wife has COPD so the recirculatory is also in frequent use. And I think it slows the buildup of "muck" on the inside of the windscreen. Chris.S.
