The A/C in my 2000GC hisses alot, Both front and back. Front blows ice cold but, it seems like the rear A/C isn't as cold as it should be. Any ideas?

 

low freon

 

Thanks, that is what I thought. However, it was doing this before and after I brought it in andI had it checked. Theysaid it was slightly low and topped it off. The weather that day was in the ninetys and they did the work outside. Do you think maybee the high outside heat may have given them a higher pessure reading?
