what year is it? usually its the pressure switch located under the front undertray the one with pop rivets holding it in near to compressor unscrew it its on a schrader valve so no gas will come out, then go and get ripped off at Renault £107.00 for a new one! have the air con re gassed and cleaned properly then take your car in to Renault and ask them to re prorgram the ecu as this controls the air con not a relay, however by the battery and and tucked away is a fuse board you can see half a dozen or so large fuses ignore these and you will see a black sealed box above this contains more fuses its fuse number 2 if its blown but very much doubt it.......Read on if your gas gets low or pressure switch fails very very common on scenics it will send a signal to ecu telling it to stop the pump from working and the only way to get it turned on is by Renault and they charge £49 for the privelige
it is relay number 4 in the fuse box under the hood
The gas seeps out slowly but you should have it refilled every couple of years
It is on the top righthand side at the back of the engine compartment.
At the Renault Parts website, you can purchase car parts such as brake disc screws, air con pressure sensors and bulb kits. For a full listing of parts available, visit the Renault Parts website.
the most likely reason is that the gas pressure is too low.Get the gas topped up at an AC specialist.
open the rear boot and pull out the spare wheel, then use a metal detector to search for the fuses as they get lost in there ,
Air-Con? Do you mean Air Conditioning?
It is underneath the drivers seat, a big blue button. If you press it the air con takes a while to stop but it works eventually :)
The duration of Con Air is 1.92 hours.
Its o/s front in line with the steering wheel with a high side port (bigger one) Renault changed the low side port for a high side fitting to stop diy fitting and re gassing, Which is strongly not advised go and get it emptied and weighed cleaned and re gassed. as a connector will cost around £19 by the time you have wasted money and time on gas its not worth it kwik fit re gas for £45 hope this helps
Dunno for sure but there's a very useful explanation for lag 2 air con control unit light on Renault forum, with pictures! worked a treat for mine.
Yes, The Air con shuts off as soon as the the car of air con i shut off. the red light just signals that the air con is ready to use.
