B.S. you don't need thousands in tools, a fews cans r134a , proper r134a charged oil, and a cheap in line guage from any auto parts store and r134a leak dectector oil if you have a leak.

Harbor Freight sells professional guages cheap and even the vacuum pump is only $150 at H.F.

Most of this can be bought at autozone for around $50-$60 and done in the parking lot with in 10 minutes.

Or just have pep boys do it for a $120, they have all the same equipment as the big rip off shops and most do quality work. For the $120 they can at least diagnose the problem if it exists and purge and refill the system properly for around a $120.

Cheaper than you going to nissan dealer that will charge you a $150 alone to just tell you whats wrong, then another $150-$300 in labor to try and fix it, plus parts.
