Hello,I have a 52plate Laguna.Had the aircon regassed as it didnt seem that cold.Did get a bit cooler,went on a longish trip yesterday and at times it didnt work at all just outside temp air blowing through.If I turn it off for a few mins and back on it was cold(not freezing) again.
Does anyone have the location of the various temp sensors,swithes in the car or engine bay.Or a fix for a simular problem.
Best Wishes Steve:steam: :steam: :steam:

just took the grill of and had a good look at the 2 pipe unions and the sensor on the condenser.all three are leaking and when you start it i can clearly see bubbles coming from the pipe unions.
these unions i gather have seals behind them?i take it i can order up from renault?also the sensor is screwed in.is there any sealant to use on these or tape like the ptfe stuff plumbers.:)

When the sustem was serviced it seems to have taken ages to empty - that was as ign of a leak whereby air was being drawn in via the leaky seals:)

Makes sense now.Anyway,I collect a seal kit tomoz and will remove the condenser Sat to give it a good overhaul,fit the seals and get it all regased.
I was thinking,when he re-gasses it,I may get the uv dye and some leak sealant added as well.What do you think???

Hi SS - when I got my air-con serviced they carried out the following
1. Emptied out any gas that was in it.
2. Check it was holding a vacuum (test for leaks)
3. Added lubricant
4. Added the correct amount of gas along with UV leak detector.
5. Ran the system checking for leaks with their yellow glasses and an ultrs-violet lamp.

The whole process took at least 90 minutes and cost £70. I had this done at a local independent air-con specialist although my local Renault dealer is currently charging
£69-99. Whow! a whole one pence cheaper.:)
