How do i lower the a/c temp in my Renault Megane expression dti?
Answers:
unless its got digital control you wont be able to and might find it needs re gassing at your local garage
Check the condenser normally located behind the radiator. If it is dirty then clean with a water hose or go to a car wash and clean with soap and high pressure water. Also check the radiator fins for dirt.
Good Luck
Just have it discharged and recharged, there is probally air in the system, as long as a/c is working there shouldn't be any leaks- maby
have (or you can) check the condensor for blockage lots of mud, bugs, or car covers / also make sure the motor temp is not getting too high.
You 'can' add an extra or larger electric cooling fan, or change the ON temp for the one you have now - the cooler you can make the condensor (*to a point) will lower your EVAP temp and the temp your ac will do.
* Lowering your EVAP temp below 32F / 0C will cause the water that develops there to freeze - and will make the system shut down / Car AC Systems lower the temp AND the humidity to cause cooling - the best you can make 'most' car AC systems do is around -40F below outside air temp IE: a 100F day will net 60F air inside under the best of conditons.
well, maybe it first had R12 gas when new it was phased out in jan 1990 due to certan hole in the ozon layer,
they use gases like 134a now which a lot kinder on the atmosphere,but dont cool as well,unless the system is designed for them,this might not make much sence,but one trick is to move the temp probe in the evaperator further towards the outlet so that it sences later,and the thermostat dont cut the power to the compresser till its cooler,but dont go to far or leave it out or the evaperater will freeze up ,all the other checks where proberly done when it was regased.good luck
if you have the cool/heat control that is red on one side and blue on the other, just move the dial so that it is not at the extreme end of the blue area, but don't have it too close to the red or you will just be cooling hot air.
