Hi Guys, The passenger window on my 84 348ss won't go up. Goes down with both switches but not back up. Was always slower than the drivers side in going up and down. Any thoughts ? Michael
First check the fuse in the passenger foot well fuse box, there should be one for each door. Then, check the door harness in between the door and car. There is a turn-off connector there. I am betting corroded connector or the connector pulled from the back of the connector. I had the same issue. --Mike
I had the same problem, this link might help www.ferrarichat.com/forum/showthread.php?t=245239&highlight=348+window+switch
checked the connectors, and fuses. all good. both switches work to send the window down so It appears to me that the motor may be shot. Also there was someone in the passengers side before me that was an absolute hack. I always wonder way people do ****ty work when it takes a little longer to do things right.
