Does anyone know the normal spec. for the low side on the A/C system? Mine seems to get cold, warm up, and get cold again. Also did just the 04's come undercharged from the factory (TSB I think), or was it the 04's and 05's?
Thanks!

 

Could anyone go out that has a guage and their A/C is working good and check their low side pressure reading so I have an idea.
Thanks
