Is there a list of the relays?

Got an air con issue at the moment, used to get nice and chilly in the cab even in the recent super hot weather then one day just hot air coming through, this was on both AC and auto
It would be temperamental over an hours commute where super cold chill then if you changed anything (blast direction, speed, temperature etc) it would go hot
Sometimes it wouldn’t go cold at all, that’s where it is now, tried to get it regassed but they said there’s no leaks as pressure tested so electrical
Checked both engine bay fuses, air con and fan but as the other components related to them are working fine I knew the two fuses would be ok as the fan adjusts as normal
I’m gonna check the high pressure switch first with a multimeter to make sure it is holding pressure with the correct reading, I can’t see the low pressure switch so guessing it’s tucked away down below
The silver canister attached to the low pressure pipes is cold both sides of the switch
I can’t get to the compressor from up top but wondering if I take the under tray panel off I might be able to access the switch and check for loose wires and check with a multimeter
So with my limited ability with electrics I’m also wondering if there are any relays to check relating to AC compressor or condenser? Battery is 12.4v in the mornings, not amazing but cranks over fine, no other issues
Had the water pump changed a few months ago by Alan in Enfield but the air con was running fine before and after, I’ve changed the water pump pulley and chain tensioner but again this was a while back, the problem only really started couple of weeks

Which relay is this, the engine compartment ones?
Ok I’ve narrowed it down to it will blow nice cold air but as soon as the centre display temp shows 24 degrees it starts blowing hot
If I first get into the car and the temperature is showing 24 or above I open the windows to bring it down to 23 or below then switch on AC and it gets nice and chilly until 24 then hot, opening the windows on the move at this point doesn’t bring the temperature down at all so it stays hot for remainder of journey
Not sure where I’m meant to be looking for a solution I figured maybe the temperature sensor was at fault/loose connection or something but I thought that was under the wing mirrors but it wouldn’t make sense why the internal temperature would come down opening the windows if it’s located externally?
Any ideas

A few issues to check with air con as explained already it may even be the compressor you may need a specialist checking it out as it won't be a diy fix unless you have the use of a gas leak tester etc mine has been off for over 4 months & with the heat waves I open the windows when I use it I'm sure the gas is gone on mine but how long is a piece of string?
