98 A/C pressure cycling switch
Where the heck do I find the pressure cycling switch on my 98 Achieva?
Thanks, Mick

Re: 98 A/C pressure cycling switch
What the heck- there is none....not designed that way- you have a variable compressor- does never cycle by design-- is quieter that way--
I assume you want the switch so you can jumper it to add refrigerant-- well no need to - just hook up your can, when system pressure hits 47 psi the compressor will kick on...but you need to find your leak--compressor belly and shaft seal are number one leak locations on the V-5 compressor you have..

Re: 98 A/C pressure cycling switch
Actually, the compressor won't run at all. I was going thru the wiring diagram in the haynes manual and eliminated any other switch or relay (they all work), and that's the conclusion I came to. Have not checked the refridgerant level yet, will do that soon.'
Thanks, Mick
