Heater won't work and power windows don't work at time

Power windows and heater fan quits working for long lengths of time. When this happens gauges do not work and theft lite and battery lite comes on. Has anybody had this problem.Thanks

Check out the ignition switch. One way is see if you have power to the fuses that control what you lost.

Make sure your belt is on at the right tension and check your power cable to your starter for corrosion. good luck.
