I disconnected my battery to look at an work on my alternator. Now the windows will not work at all ive check the fuses everything is fine, why won't my windows work?

After a loss of battery power, it'll often be necessary to "re-initialize" the system. 1. Close the door for the window being reinitialized. 2. Turn ON the ignition, with the engine OFF. 3. Hold the window switch up for two seconds after the window is closed, release the switch, then hold the switch up again for two seconds. 4. Lower the window all the way down and hold the switch down for two seconds. 5. Repeat the procedure for each window, including the rear quarter windows on convertible models, until all windows are initialized. Give this a shot. If this does not work, then you'll need to obtain some assistance at a shop near you. Use this link to find some shops near you that can help with your concern: www.repairpal.com/repair-shops
