said by Xstar_Lumini:my 97 grand prix didnt have dual zone either, but it had 2 blend doors as if it did. a proper shop in canada cant top it up with refrigerant without checking for a leak.
Okay and how do I go about in fixing the problem and much money will this cost me at a shop?
P.S. my minivan does not have climate control or back air conditioner, its a 1998 and has 5 vents only at the front.
