Air Con high pressure switch

My air conditioning has gone intermittent, when I tap the high pressure switch which is located on top of the receiver dryer, it starts to work again, is it possible to change this switch with out having to recharge the system.

no...
you have to vac down the system to do this,and you have to buy the whole receiver/drier because the swich is combined with this,prive from ford parts is £77.36,i know this because i ordered one on thursday

PS you really need to get the item replaced by the pro's as well

hiya.
first the good news! 
the switch is available on it's own, but at a ridiculous price!! it does NOT  come as part of the reveiver / drier.
it just screws into the top of it...easy peasy.
mine had been 'bypassed' (previous owner!!) by joing one pair of the wires together previously. there are 4 wires, 2 'pairs', and a fault on either 'side' of the switch will cause problems. not recommended to run the aircon with it bypassed, as you would have no over-pressure, or under-pressure protection  .
had to change compressor on mine, so a new receiver/drier was needed. It doesn't come with the switch either, as they expect you use the old one!
a pain in the butt, but not a hard job. If i remember right, the system did not need to be de-pressurised, but would recommend you check this first 
good luck!

Surely in a system that's only used a few weeks a year one would expect the reciever/drier to last indefinately rather than have a life expectancy.
Well, mines 9 year old and still going strong, crossing legs while touching wood and throwing lucky black cat over my left shoulder.

hi there
i for one run the a/c all year round. when it's wet/damp, it helps keep the windows mist free.
re the dryer. it is a silica gel type filter. it's to remove moisture from the system. once it 'full', you start getting the pressure problems ie fans running on fast mode etc.
remember it should be regased every 2 to 3 years and the pollen filters changed every 6 months to a year. a shot of anti-bacterial spray to keep the air conditioning pipes clean once a year is a good idea too.

i have to agree with scorpio man here,you really should run the cc all year round,or AT THE VERY LEAST once a month,failure to do this can make the seals become hard and brittle,then when you do decide to use the climate,you will end up losing the gas through the damaged seals.......

thanks craig.
taken what you said on-board.
guess it depends where you source them from!
Mine did NOT come with switch (brand new, sourced from my motor factor's (i work there!) suppliers). switch was only available from ford. I got one off a member of this forum. works fine  .
All work on 'pressure' side was done by local air con engineer...........quite easy, if you have the equipment. No problem to get for trade, but don't think you could get it if not!

I also run my system all year round, I agree it does help keep the car mist free. I had a new Dryer Filter last year with a new compresser. I now have a new presure switch and have been told by a mechanic that it should be ok to unscrew the old one and replace it. But just in case its not, I think I will leave it to the experts.  I let you know what happens.

Just an update to say I have fit the switch myself, very difficult to get a 17mm spanner in there, the system seals it self as you unscrew it, makes a little pop. Then when you screw new one in it make's a slight hiss. Working fine now. Many thanks Chris.

If the Receiver drier is a silica gel container then surely these can be recyled, after all it must be possible to dry it out and seal and save it for the next change required, if you intend to keep the car for a long time!
Yeah i know I am a "Tightwad"!!!
