As nice the Coupe is, if you live on the Pacific coast, don't expect too much about front windshield defogging unless the cabin is warmed up and never use recirculation when it is raining.

All the windows will be suddenly fogged again in a matter of seconds. If it happens on the road, you will be in serious trouble. I know because it happened today.

Windshield defroster is very slow because the engine takes time to warm up in the morning at about 40 degrees.

 

Thanks for the heads up, never had an issue in my coupe or convertible. Let the MINI warm up a bit before you drive off. My heats up pretty quick compared to the R52. Have you tired the Rain X interior defogger? Couple people in high humid areas like FL and the Bahamas use this.

 

You could always try the rain-x treatment to see if that helps with your fog issue.

 

Air conditioners dehumidify the air.

Are you running the AC?

 

You may have a very good point. My A/C has always been running on all my cars even in winter but I was living in the desert.

Here in WA Peninsula it is mostly 95 humidity all the time, mostly raining and in the low 40s,

 

Thanks, I will also try.

 

" Have you tired the Rain X interior defogger? "


Mentioned that above, I have used it before , you have to reapply a couple times a year. It works the only thing is the spots you missed will get very hazy on fog up , so you will see them.

 

Here in northern Yurp, the A/C which I don't have much other use for in my Roadster is almost essential for drying the air in rainy weather to keep the glass clear.

Oh, and if that is too slow, the 'defog' button also switches on my heated windscreen and nothing beats that......

 

We don't have heated windshields :(

Range Rover gets it, Rolls Royce (sides also) gets it , Some Merc's, all in the US. But MINI..... it messes with the easy pass system I was told.

 

Interesting. This just started happening on our clubman (115k and many winters). It's so bad we have to leave the a window opened a bit. Never had that issue with it before nor on our hardtop (50k and a few winters). We haven't driven the coupe in the cold yet. I'm wondering if something is preventing fresh air from getting in.

 

If your MINI is on recirculate all the time w/out air. Then you will get some moisture build up .

 

We had a coastal frost overnight. It took about 10 minutes with A/C on at full defrost and blower speed set ups with the rear window defogger on to clear the windshield and side windows. The side mirrors were just starting to clear up.

My feeling is the charging system is very weak with full accessories on and the battery is very small from what I have been told, I have to admit I never looked.

I also observed the engine is slow to start in the morning.

What is the experience of other MINI owners in cold climate?

 

I'm having other issues right now but I know the owner's manual always recommends having the a/c on regardless of temperature because it dries the air first.

 

We had some cold days , but had many BMW's ( 5 ser and 3 ser ) in the past , among other cars and the R58 is the same on start up when very cold.

You were out in vegas and batteries do not last as much out there. Heat kills them . get the battery voltage checked.
