2003 Cadillac Escalade
This is the original equipment part for the vehicle. I do not know why it said it would NOT fit my vehicle when in fact it does. I installed it and it fixed the cycling compressor issue.

Solved my ac issue
Easy to install and stopped my intermittent ac issue. Ac would work great and would suddenly stop working . Had it recharged and that didn’t help . Found out that the part was failing . Cheap and easy fix !

Works great!
Change this part first if a/c is blowing hot air. Use OEM or AC Delco parts when dealing with engine parts.

This fixed my 2005 Chevy 2500HD
05 2500hd pickup 6.0 with 207k miles. All of the sudden, AC started having an issue where it would blow cold for a few minutes after start up, then the compressor would turn off. I disconnected the wire to the pressure switch, and I used a jumper wire to bypass the switch to see if the compressor would kick back on. Thankfully it did. I bought the new switch and had working AC again within a minute of opening the package. Remove wire Remove old switch with 16 mm wrench. Change out the o-ring Put on new switch Reconnect wire Tell wife to fetch you a beer.

Good part just make sure it fits your vehicle. Amazon will say it fits but when you go to install it might have a different connection.

Works well, correct part for low pressure switch.
This item was very easy to install (took about a min.). It does come with the O-ring. So far it has fixed it issue of the compressor not turning on. I will update if/when the item fails.

Exact fit/ Good quality
Installed on my 2005 Silverado 2500hd with the 6.0 engine. Fit perfect, took 1 minute to install. Came with 1 rubber seal gasket. Didn’t fix my ac issue but the part did fit.
