I have this strange problem with my 96 Honda Civic DX manual transmission. No mechanic has been able to give any explanation.

Sometimes the steering of my car becomes extremely soft (there is very less traction when I try to turn the car), and the turn signal won't shut off after turn. That is after a left turn, when steering is turned clockwise the turn signal should go back to central position. There are audible clicks when steering is going to initial "straight" position after turn in good working cars.
Where as in my car, steering becomes very soft and there are no clicks when I turn my steering back to "straight" position.

This problem goes away by itself in summer and reappears in winter.

Any clue what could be wrong, I don't have much idea about steering of honda civic.

Thanks
