WTF!!!!!!!!

This is my problem, last night i was hittin switches(maybe for 30 seconds), then all of a sudden the front would not lift and the bak was sitting all the way up, when i hit the switch to let the front up i would hear nothing but air going out of my dump valve(car would not raise) when i would try to let the back down i would hear air leaving the dump valve but the back would lift right back up, i managed to drive the car home, i felt my valves in the front and the dump valve was really hot but the fill valve was cool, after about 10 minutes the back of my car just dropped for no reason after about 5 minutes the switchbox went to SMOKING, so i disconnected the power to the switch box to stop the current. can someone tell me what is going on?????????

P.S. is it possible that my valves maybe damaged due to heat. Thz

P.S. in my opinion its sounding like the switchbox is the problem.
