MDC one-touch window module failed

3 posts in this topic

In 2006, I purchased the Ultimate Window Package from SmartieParts for my smart fortwo. A year ago or more, one window started behaving oddly. The dealer got it working properly, and it lasted for some considerable time. Two weeks ago, the dealer's tech again had a go at it, since it would not operate at all. He got it working, and put di-electric grease on the connectors. He said that the window operated o/k without the aftermarket module in the circuit before he cleaned the connectors. His advice was to replace the module if it happened again. Yesterday, the window would only go up, not down, and once it was up, it would not open again. I did not do the original installation myself, but I assume that the module that the tech was referring to is the one-touch module. SmartieParts no longer carries this item, but I asked Steven for assistance in the task of procuring a replacement. He responded quickly, but unfortunately, was not able to offer much hope that a replacement could be found. The failure of this component is apparently common, and new MDC examples have failed to perform right out of the box. I am now disabled, and have hand controls on the car. The one-touch feature is important, since my left hand is utilized operating the brakes and the throttle. Single touch window operation allows me to control the windows without needing tie up my hand to hold the button down.I understand that the 451 model has one-touch window operation. I presume that this functionality is built into the switch itself. Can anyone with experience give me their opinion of the idea of adapting a 451 switch for use in my 450?

Thanks for your reply. I missed it until today when I decided to bring the subject up-to-date.I decided to remove the module and take it to an electronics specialist to see if they could repair it or come up with a replacement. The SmartieParts detailed installation instructions that I had in my possession showed that the module is easily accessible from the inside of the door. When I went to remove the connector from the back of the window button, the window sprang into action (the keyless window operation module makes the system always ready to go). I withdrew the plug and then reinserted it, to see that the connectors were completely reseated. Conclusion: there is nothing wrong with the one-touch module; the problem appears to have been simply a bad connection at the OEM switch. I didn't do anything at all to the one-touch module. So much for relying on the opinion of the M-B technician. It's always nice to be able to say "I fixed it myself".
