Just had a problem with my drivers side door switch cluster (some windows went down but not up). Replaced the cluster, and all works well now, but, on the cluster is what I belive is an over current protection device, perhaps yours is bad, and you end up drawing too much current which blows the fuse.
To troubleshoot a little, if you remove the cluster, there are 3 plugs, two larger ones, 1 smaller one. The two larger ones are for the windows (1 for the front windows, the other for the rear). You could disconnect 1 for a while and see if the problem occurs, then reconnect it, and disconnect the other one.
A new cluster sw. cost me $137.
