I am out in Hong Kong.... where it is HOT and humid.....

The cool harness is great. JimF gave LOTS of support to me while trying to figure what was the problem I had with the car. No fuss, no hassle.... i properly gave him more hassle than what the CH is worth! I have the CH-92.

I have the early 92 W140 model. Just the M104 3.2 litre.

The Cool Harness will help you with the heat. Your fans will run properly non-stop like mine but it will only mean wearing out the fan motor which is a replacement item anyway. My alternator did went out few weeks after the Cool Harness. I think the break down did not relate to the Cool Harness but the use of it have made the problem surface a lot quicker. As we all know, alternator break down in stages and takes about a few months to completely die!

Your fans turn when you have the A/C on anyway so don't worry about strain on the power system. Jim confirmed to me that my head lights use more power than the fans! I did notice that if I have the A/C on, lights on, fog light (front and rear) on, the rear window de-fog on, radio on and with the aux-fan running, the reading on my multi-meter falls to 12.3v and lower... No big deal, I just test the limit and avoid turning everything on at the same time....

the next thing to fix is my close assist pump which I am trying to run a wire from the boot to the cabin and reset the pump from inside the cabin when the pump go south! Still trying to locate a hole on the rear firewall...

not to mention a lose part in the rear view mirror which I am trying to get help from members here...

Did you also use the Water Wetter along with the CH-92?

Have you changed the wiring harness or a/c evaporator yet on your car?

Any problems with the sunroof?

How are the dealerships over there? Very helpful or not?

dealers here are a joke. It really is. Can you believe they charge 20000+ USD for replacing the front suspension of a W220!! YES its 20K not 2K!!!

My evaporator has been changed 5 years ago. Hope it will stay good. But nowadays, a lot of independent tech can replace it so I am not too worried. At least I can fix it under realistic price.

I don't have a sun roof. One ledd thing to fix. Yours having problems. Make sure you lube it with ONLY mercedes benz sun roof rail lube or what ever they call it. Anything else will ruin it as I have read...

Wiring harness.. nothing yet. Fingers cross.

My tech said I have some problems with the computer that control my idle speed. The piece that connects with the air-flow meter. Basically my car will stall if I do a FULL turn, stressing the power steering pump to max. well I don't have a problem not turning it to max. In fact, I never do, my tect did it and it stalled on him!

I don't have access to Water Wetter. But with what I have I am happy enough. I don't want to drain my system when Winter comes where I do need some heat to stay at 80 degree
