Cab Battery Change Heads Up

Recommended Posts

I have often seen reference on RennTech to "re-training" the windows on these cars, but had never encountered the need. Today, I changed my battery .... defensively, as the old one was 5+ years old, and Loren warned me I was headed for a failure. (thanks, Loren, by the way, for the Costco battery recommendation. With instant rebate, it was only $39.)

Change went without the most feared hitch: my radio code worked without a problem. However, the driver's window on my Cab was down in the "door open" position when I closed the door to drive off. When I re-opened the door, it dropped even further to a never before seen level. The pax window was in normal position.

The answer? I had left the driver's door open while the battery was disconnected, then reconnected. Thus, it seems clear that the driver's window "learned" a new top position while sitting in the drooped "door open" position as it should have been with that door standing open.

Remembering all those RennTech posts, I sat down, closed the door, turned on the ignition and ran the window all the way down, then all the way up. Presto! It was retrained. Thanks once again to you guys for saving me trouble & money.
