Top operations
Top operations
Top had developed some leaks in the cylinders. Replaced all cylinders, latches and pump through Top Hydraulics ( great folks to deal with). So now when I turn the key on the top operations switch light flashes. When I unlock the D latch the windows do not go down. No sounds of any latches operating when you press switch. Any suggestions?
Thanks

Re: Top operations
When you release the latch from the window frame, a switch closes and grounds a pin in the connector of top control module (C1-16). The TCM then sends a data stream on the CAN BUS to the BCM telling it to lower the windows. But that is not happening...
YOu were back there messing around, is the cable plugged into the TCM? Either the TCM is not talking to the BCM or the ground that should be on C1-16 is not there when you turn the D Handle.
