telescope issue
 

It can only be one of 3 things: switch, fuse, motor.
I would bet the fuse is good since the tilt works.
Start with the switch, then supply power to the motor to test it.
Post your results so we can gain from your knowledge.

it was option 4 ,, just SAM module not talking to system,mecanic say , fuse, motor,switch was all ok.
