[QUOTE="MW51, post: 583535, member: 3432"] maxion89, Speaking of your aircon not cold. 1. You might need to check if your aux fan is working when the aircon is switched on. Try to do this test and check when the car is cold (says first start in the morning) so that the aux fan is not controlled by the radiator temperature. Start the car then switch on the aircon, go to the car front end and check if the aux fan is running under low speed. If yes, it is OK. If not, 1a. Check the fuses, they might have blown; 1b. If all fuses are OK. It might be the aux fan low speed relay faulty. (The yellow one with five pins in the aux fan relay box) 2. Check if the aircon gas is adequate. (Usually done bu outside mechanics) All the best to you. [/QUOTE]
