1. Could be a caught foreign object between A/C (air conditioning) fan and cooling radiator, producing this loud noise. 2. Could be a damaged fan blade, mowing the cooling radiator. 3. Could be a loud noise comming from the fan's electrical motor. 4. Could be a broken off fin (small wing) of the cooling radiator, striking the A/C fan, producing this loud noise.
Hello there, As far as the check engine light I would think since you mentioned it shacking that your light will probably be on for a misfire, Meaning most likely you have a spark plug wire going bad. I would stop by somewhere such as Autozone for a free check to tell you why your light is on just to double check.
Your fan issue could be several different things such as the fan motor going bad or the blades could be rubbing something, that one is a little tricky without hearing it.
Good Luck and I hope this does help you some. Allen
It may be the thermo fans that are on the car.They cut in and out especially if the air/con is on.The car will have a belt driven fan but the electric thermo fan,will cut in and out as it is needed creating a highspeed fan noise.Hope this is the problem and helps you.
the a/c when running creates a lot of extra heat and needs second fan, if second fan is not working right this will cause overheating, if fan is creating a load noise it is likely bearing is bad and will not spin as fast as it should not cooling. also check that fan it not hitting anything if you describe loud noise i can give better idea
I would check the radiator fan in the car for looseness. If the fan wobbles or moves , Then change out the radiator fan. The radiator fan and motor come as one piece. There is a fan relay also should be replaced.
When turning the key only half way to make the dash fan work, indicates that the dash fan is okay.
The dash fan may make a whining or high pitch noise when engage. Then I would change it out because an internal bearing to the fan is going out.
