thank you so much for your help guys.. yeah, they actually did say that i had a leak. but, i just talked to xterraparts.com and they actually had two in stock!! so i have the part ordered, now all i have to do is get it and find a place that will do it for me. or is it something that is easy to fix?

also, b/c of the leak, i probably have to get it recharged and fixed.. so maybe i should just bring it to a mechanic.. right?
