A/C low pressure switch 07 GT

[Redcore]

I did a search and wasn't able to find anything here, so I'm hoping that someone could assist me.

I have had the switch replaced 2 times by an A/C shop, so I know that's what is going bad. However, I'm not sure why it keeps going bad. On my trip from Florida to Idaho before I left for my deployment, it went out again. Can anyone tell me what in the A/C unit might be causing this issue? This way once I return I can fix the issue once and for all.

Thanks.

Really haven't seen any problems with this switch failing on cars like yours. Could be you just got a bad part. More common on these cars is the compressor clutch relay which would have about the same symptoms if it were failing.

Yeah. That was my first assumption before I took it in. But they found that the low pressure switch was bad. They replaced it. About 4 months after having it replaced, it did the exact same thing again.
