OK, I am a newbie to the Del Sol and am trying to tackle this without a mechanic, any and all help appreciated. The other week my windows (all three) stopped rolling up/down on my 1997 Del Sol. I checked the fuses and they looked fine, and I noticed all three controls in the switch will cause the "click" to happen in the power window control (loud audible clicking noise.) Checked to make sure harness in/out of control unit looked good, etc. Ordered new control unit for $20ish, replaced it, and the windows rolled up/down for about 30 seconds then stopped again, back to "click" only. I have perused the forums I can find on the subject, any help appreciated. Thanks!
