saintluci,

AFAIK kahit okay ang menor mo kung naka-off ang AC, basta hindi normal and idle speed kapag naka AC ka, there's a possibility it's a servo kit problem.

Sorry I have no idea how much a servo kit for your car is. Normally kung brand new yan aabot ka ng around 10K.

tanong-tanong ka muna baka may mas mura pa.

HTH
