For quite some time now...whenever i turn on my a/c before leaving the garage/parking or when the engine is still cold, i hear this screeching sound from the engine bay...i have tried retightening the belts up to the point of having them replaced to no avail...i still have the problem now. i already had the a/c checked by mang mario, including the pulleys, they're all ok...and by the time i get there, the screeching have gone away (usually after 10mins of driving nawawala). i don't hear the sound pag walang aircon huh!

whenever this happens, there's also a heavier feel to the steering that sometimes i cannot manuever/turn the wheels (happen in eastwood - i was not able to steer to the left/right until i turned off my ac...naulit ito nang mga ilang beses pa. but once i'm no the road, ok na ang steering, parang sa unang pihit lang talaga at full turn and pihit.

could this be a power steering problem? is there such a thing na mejo mahina na ang power steering pump?

any advice would greatly be appreciated

TIA
