2010 Murano Not cold, maybe Drier?

[atrdriver]

I have a 2010 Nissan Murano that I had to pull the AC compressor a few times in order to replace the alternator. The first two times after an evac and recharge the AC worked great . After the third time it's not blowing cold (Yes I had to put 3 alternators in this thing). Gauges say 200/35 when compressor is running, which I think tells me it is full of R-134A. I'm thinking it could be the drier, but it's really a pain to get to so I kind of want to confirm that before I tear it apart. Is that what it sounds like?

Thanks in advance

Reclaim the refrigerant and add back the proper amount to know you have the correct amounts for further analysis.

Refrigerant

Type .................... HFC-134a (R-134a)
Capacities


Refrigerant

Capacity .................... 0.60 kg (1.32 lb)

What Tim is saying is that pressures alone do not give a true indication of proper charge.
And any pressure readings s/b taken at 1500RPM, max fan, max cool, windows open, 80F day or hotter. ie a real load test. And the test conditions should be specified in your post

I will refill it with 1.32 lbs tomorrow and let you know what happens. Thanks for the replies.

Thanks guys. Apparently I didn't have quite enough R-134A in it. After a vacuum and refill weighing the cans I have a 38 degree drop from ambient, and she is very happy with that. I appreciate the assistance !!

Thanks again

Glad it worked out, nice work

I'm back in !!!

I guess I'm a little smarter than I was yesterday, and this morning I Googled how to set up an "exception" to the site URL in Avast, so now I can get in to the site !!! SUCCESS !!!

Anyway, my comment is that one will never get a full 12 oz. from a refrigerant can; I figure 10 to 10.5 oz. actually get into the system. I have no idea how much refrigerant ends up contained in the hoses either.

Cusser, we wondered where you went! Welcome back

BTW the hi side hose holds between 1.5-2 oz

Hope John is all right. I have not seen him lately—as well as GM Tech, Brad, Detroit, and others.

I was thinking the same.
I suspect John took a week off due to Mem Day weekend
