W124 Blower Motor Override?
First I did a search and was unable to locate anything on this.
Is there a way to convert the stupid fan control to low, medium, high as opposed to low, auto, High? The auto function is rarely below high and low is often too low. Anyone know of a simple fix? Chris

Electronic engineer here to save the day.
How bad do you want one?
I can custom engineer almost anything. The easiest mod would be to use the auto button as a mid speed. Could do more but would require additional control installed. I can make it as simple send me your Climate control module and in 2 or 3 days I will send back modified version. Or I could send a schematic with a parts list and instructions. What do ya think? How much is it worth to you. Anthony Bridges |

Anthony!! I dont know exactly whats it worth, ya got me there!! But I wasnt really sure what was involved, I was hoping itwas rather simple but maybe not. What you stated is exactly what Im loooking for though, to make the middle switch a medium fan setting and leaving the other two the way they are. Either way communicate with me here or at badbenz94@yahoo.com.
Thanks!! Chris

I find this a bit frustrating as well... it seems like you have to play with the rheostat wheel to much just to get the right fan speed.

Climate Control
Yeah, climate control is nice when it works, but when the pushbuttons and thumb wheel get old and start to fail you are left with either no air or jumbo jet noise.
I had some luck resoldering on the pushbutton connections on one unit and getting it to work again but ended up replacing the controller for big $ on my other car. |

You asked for it you got it.
I will work on this project next weekend or when time permits. I have been working 7 days a week lately and time is something I have little of. I will put together an instruction manual for doing this modification. It will have lots of pictures to make it easy. But be prepared to use that soldering iron!...
It will cost me some investment to do this as I am going to buy a couple of used Climate control units to experientment with. Also I am working on a kit that will improve gas milage from 20% - 40% would you be interested in this kit? The prelim cost is around 250.00 - 600.00 diy kit. Kit will have a DC motor, controller and a custom bracket and 2 belts. As we all know when you run your air conditioner you get lower gas milage, but did you also know that the water pump, power steering pump, polution control pump cause drag on your engine? I am working on a kit that will power your Water pump, Air conditioning, Power steering and Polution devices from a dc variable speed motor that is controlled via Engine rpms. This way all pullys will turn the same speed as the motor. I can see 24mpg highway turn into 31.2mpg or more. I have the motor and controller and I am installing on my car for testing. It will probably take 2 - 3 months of development. Initial average cost savings estimate, 12,000 m/year driver is around $287.00 at 2.50/gal at 3.00/gal. it is $345.00 if you drive twice as much as I do you would save double. Not only will you save gas but you will improve horse power, when you want to stomp on it. Will keep you informed with regular postings. Thanks Anthony Bridges |

One question. How will your idea actually save gas? Running the accessories with a DC motor is all well and good, but where does the electricity for the motor come from? Regardless of your power source, the accessories will still require the same energy to turn, whether this comes from the engine directly, or from the engine via electricity generated in the alternator.
I guess that was two questions.

Actually quite a few folks have already engineered setups like this for battery electric vehicles, since a lot of parts like brakes, air conditioning, vacuum pumps, and power steering require constant rotary power inputs which you don't have on an electric vehicle. The mechanical belt linkages are normally not preferred, since they take up space, vibrate, make noise and are generally troublesome. Mostly they go right to DC electric driven components for vacuum, water pump, etc. The exception is the compressor for A/C, usually that is driven by a closely coupled belt or a direct shaft coupling, but it eats a lot of power. Hope these links help!

After market products
There are a lot of after market products out there already such as dc motor powered waterpumps that claims to increase your horse power 18 -20%.
I am still in the design stage. Without giving away the farm all I can say is that there is a way to do this. The problem is to find an inexpensive way to bring it to market that is cost effective. The price of gas gives me the incentive to experiment and see what can be done. I understand your question. Power is power in one form or another you can't take away from one (combustion engine). to feed the other (ALT and DC supply) and recieve an increase in power, but have you not heard of gear ratios and PWM controllers? You can lift a lot more weight if you have a bigger lever with the same horsepower. Thanks for the link Jim!

These types of modifications are useful if you are trying to increase peak horsepower. For example, air cooled Porsches sometimes convert the belt driven cooling fan to electric because it uses significant power at high rpm. This does not help the average mileage, but allows you to get maximum power for short periods of time. |

You guys don't see the picture here.
You dont see the picture here nor understand where I am going to get the energy savings from but I do!.
I will let you know how it is done after I have completed my tests and hopefully if it goes well apply for a pat. I did take physics in college allong with calculus and electronics from 2 year tech school. You are correct Moneypit and Craig "every time you convert from one form of energy to another, you suffer a loss based on the efficiency of the conversion" but there is a way to do this.... Think about it....... I have spent several days coming up with my solution and now its time to test it. Thanks for the posts! Anthony Bridges |
