guys, you know the two fans at the engine area...normally does the right fan run slower than the left fan? (left is car battery/air filter side, right is timing belt side)

mine...right one is slower...much slower. Wondering if that thing rosak. Air cond sometimes hot when stuck in traffic jam.

last time sent to check before but mechanic couldn't find problem. Coz it only happen occasionally...during traffic jam. At the shop, it was working fine so they couldn't see what the problem was.

morning all
