which one is it?
With all the hot weather we've been having lately, I'm thinking my AC isn't working as well as it used to. Being a 2001 with over 200k, I can imaging that the R134a is lower than what it was from the factory. So I'd like to check the R134a pressures to see if it is low or if it is old-timers kicking in.
I was able to get a set of gauges and have located the high pressure service port on the right front corner. However, where is the low pressure port? I've traced both hoses from the compressor all the way to the firewall and I only see 2 ports, both on the same hose (see attached). One has interior threads and is on the expected high pressure fitting.
I also have been reading in another thread that the Bonne'* have a higher pressure than some of its counterparts. Does anyone have the temperature/pressure chart that covers the 2001?
Thanks for setting me straight.
