just have some questions on my car i've only had for 1 year.

Bought this car last june 2009....everything been great til these past 2 months...i replaced fuel pump, heater hose / coolant pipe, due to a leak, and now all of a sudden when i turn my a/c on its blowing hot air, then my car tends to want to run hot "h".... But if i turn the a/c off after a while of driving it, it will run "h" then drop down to normal after a min or so.... I really need some one to help me on what could this reason be....

 

are your electic fans working...i'd check those first...

 

have u replaced the thermostat at all? could be stickin, only evident when the AC is running?

 

Check the electric fan relays. If the fans are not working properly you'll run hotter than normal.

 

Thanks i got this issue fixed
