The passenger side fan should only come on while driving at highway speeds, to offer additional cooling help to cool down car, the Driver side fan is for when parked, ideling, city traffic, and air conditioner use. At least that is what i was told.
That is very vague. Have you checked the radiator, and when it is hot does the electric cooling fan come on? Try running the A/C and see if the cooling fan comes on. Does it run hot on the highway or just in city traffic? I need some more details to try and narrow it down. There are many things it could be. Low coolant, stuck thermostat, air in the cooling system, bad fan motor, fan motor relay (also known as fan switch), or temp sensor.
Hello, You need to have the charging system checked with the A/C on. There are several things that are different with the A/C on. Most likely you have a marginal Alternator. Autozone, Advance and Oreillys give free tests.
When you turn on the A/C, the compressor can increase the drag on the belt that drives the Alternator. A weak Tensioner pulley or a stretched belt can slip around the Alternator pulley, reducing the charge capabilities. The Electric engine cooling fan is usually stepped up to high speed when the A/C is on, therefore using more juice.
Since your car is discharging at high speeds, the idle step-up feature may still be working when the A/C is on. The idle step-up is suppose to maintain a minimum idle speed to compensate for the A/C drag at idle. As long as you are not caught in slow traffic, your battery should recover by the high speed driving.
Your blower fan could be drawing a little more power too, but fuses should blow to prevent the blower fan from drainng your system.
I will recommend a Web site, car-parts.com for Salvage parts. You need to count the grooves on the pulleys as they are important and illustrated as 4G and 6G for a 4 and 6 groove part. It is possibly to buy a stronger Alternator for your car.
HI there #1 before you put freon in did use a vacuum pump and pull too the right vacuum specification if not you have air in the system. #2 if you put 4 cans of freon you over charged the system must vehicles a/c systems use 1lp 5oz you must remove freon first and use vacuum pump and put system in vacuum for abut 1hour too mack shore system is air and muster free. ones that is don you can charge system be careful not too over charge OK
In stop and go traffic will normally cause a car/truck to heat up more using the a/c. The most common cause is low coolant in radiator or a sticking thermostat. Check the coolant in radiator and check the front of radiator for any restriction to the air fins on radiator causing a blockage to keep the air from cooling the radiator. Check the clutch fan when cold by turning it by hand, if it turns free it will be ok. If you had run the truck and the coolant is hot try turning the fan by hand and if it turns free at that point the fan will be no good. Replace the fan. Hope this will help you.
This will be caused by either a bad compressor, which is probably not your problem on a newer truck, or a low refrigerant charge. At higher speeds the compressor is working harder and pushing the refrigerant faster through the system and if the charge is low, it will run out of refrigerant and stop cooling until its can get more gas. A clogged dryer/receiver or orifice tube can also cause this but, again, that will usually happen on an older vehicle.
