I'ts starting to warm up here in Ontario and i have no air conditioning!!

How do i tell if its just a re-fill needed of freon, or something more serious?

Last September, it worked on-and-off, but now, when i turn it on, it starts off a little bit cool, then blows warm, more on the passenger than the driver.

When i did the diagnostic using the buttons on the A/C, its runs off about 15 errors.


Thanks in advance,

 

Have you checked what the codes are? That would be the best place to start.
