A/c compresor not engaging


Yes, freon must be present in the system in order to circulate the oil that lubricates your compressor. A low pressure switch is used to stop the compressor from running if the freon level/pressure is low. This is to keep your compressor from destroying itself due to lack of lubrication.

There are also several other reasons that an A/C compressor will not engage. Proper diagnosis is required.

My hyundai elantra keep ticking wat can i do to stop the noise


A "ticking" noise can be caused by several things. First thing to check is the oil level. When an engine is low on oil, there's a lack of lubrication and you will hear the lifters "ticking". Some cars make a "ticking" noise with the AC on. The ticking is the compressor kicking on and off.

Air condition stopped blowing cold was working great before i cut it off then when restart from oil change blowing warm-1995 regal 3.8


Did you change the oil yourself?? If not I would return it to the service station that serviced your vehicle and file a complaint with management. There is either a leak in the ac system somewhere casuing a loss of all refridgerants, or maybe the belt has come loose. Also your ac could be lacking if excessive amounts of oil or other lubricant had gotten on the belt.

Grinding sound when running a mechanic said its timing chain..


First question. IS IT NOISY ONLY WHEN THE A/C IS ON ? If yes , its the compressor, if not could ne the A/C compressor clutch bearing. Best found using a " mechanics " stethoscope such as a doctor uses to pinpoint the noise. Hope this helps

Noise from A/C Compressor


Hi,it is allways better to remove the compresor ,do to the lack of room to work on the engine compartment,by what you are telling me it sounds like your compresor is bad you may try to replace the bearing but you may found the compresor on line for the same price with less troubles. good luck.C1
