Very weird glitch steering servo

[Toiffel]

Maybe someone can give me some help here....
I have a Ko Propo Mars radio, standard JR servo for throttle and a Hitec 625 MG for steering, everything was working great until today, while i was warming up the buggy I noticed that like magic I would the steering was gone, nothing, I would turn the wheel on the radio and nothing would happen, but I would still have throttle ( I thought maybe the failsafe kicked in) also it would lock the wheels to the left, and after a while it wouldwork a couple of seconds, and then again, I tried first switching servos, nothing.... switched receiver, nothing... switched crystals, nothing.... checked receiver battery, and nothing.... same exact problem....
The only thing left is trying with another radio..... Has anyone had this problem?? Any clue what it could be??
Thanks for the help.....

i had a hitec 605 bb burn up on me. i had the same problems. i took it apart and the circuit board was burnt and wires came unsoldered. the motor was real hard to turn in one direction aswell. i found out later that my servo saver seized (say that 3 times fast:D ), likely causeing it to fail.

I think I found the problem, I believe it was the receiver battery connector, it was very loose, I put a new one in, and tested it (car not running) and everything worked fine, the final test will come this Friday....
Thanks
