Low Pressure Switch on a '98
Long and Short---Lady at church today asked about her A/C.....working fine Sat......nothing on Sunday. Took a quick look (still in Sun. Go to Mtg. Duds) did not get on the ground to look, and noticed the low pressure switch was not on the Accum. like on my '91 Olds 98. Where is it located? I thought I'd cross the terminals quickly just to see if the Comp. still worked, as it was not this PM. Looks like I may have another complete job to do. Just want to make sure I know where all the compon. are before beginning.
Thanks

Sorry I missed this one 'till now.
The low side service port is one the suction line between the accumulator and the compressor.
This systems doesn't use a low pressure switch and a high pressure switch. It uses a Pressure Transducer that uses a variable output to the pCM that records bothe high and low pressure. The transducer is located on the compressor discharge line.
