Prius (2004-09) :: Toyota Squeal When AC Is Turned On And Off


Mar 26, 2013

Further investigation I figured it was the the flap opening and closing. Whenever I push the recirculate button to open and close the vent it squeals. Is there a way I can lubricate the vent?

Ford - Explorer :: 2004 - RPM Related Squeal Which Gets Louder If Heater / AC Fan Is Turned On

Have a 2004 Sport Trac with approx 78,000 miles. My daughter drives the vehicle around town. Approx. 2 weeks ago when she started it a loud squeal came from under the hood. I raised the hood and determined it was coming from the serpentine belt. I sprayed some lubricant on the belt and the sound went away, temporarily. I took the vehicle to a local mechanic. He thought the belt needed to be replace and did so. He showed me the old belt and commented that the old belt was in great shape and he could not determine where the sound came from. He also was able to spray lubricant on the belt and make the sound stop for a while. The squeal is definitely rpm related and also gets louder if the heater/ac fan is turned on. I have been reading alot on the internet about such problems with this vehicle and am getting really concerned. If it were the harmonic balancer would the vehicle still be operating this length of time since it started making the noise? What does replacing the harmonic balancer involve.

Prius (2004-09) :: Check Engine Light Turned On For A Few Hours Then Turned Off

I always take care of my car oil changes on time. And in the last week my check engine light turned on for a few hours then turned off. And today it turned on again. I kinda regret getting rid of my scan gauge now.

Chevrolet - Tracker :: Loud And Constant Squeal When AC Turned On

2003 Chevy Tracker (same as Suzuki Gran Vitara) v6 2.5L

For about a year, it has had belt squeal on starting, which lasts about 5 minutes..it's louder when AC was on..would go away with higher RPMs. Once the car was warmed though, no squeal. Ac has been working very well and blowing cold whole time. Finally it around to replacing belt, which was a difficult.

Tightened with an idler pulley type system(not spring loaded). Started it up, squealed a little on start, but went away..turned on AC and the squeal is horribly loud now and constant..high rpms only make it louder. Noticed that clutch engages fine, but spins inconsistently..like we'll the belt is slipping. It spins slow, fast, slow..etc. I can't tighten anymore as the tightening bolt is at the end of the channel, don't want to strip it. Also noted that it is about a bolt head width more tight than its previous position.

Surely changing the belt wouldn't cause the clutch to bite it would it?

Other notes...drives great when ac is not on. This is an acc only belt..ac,idler,power steering. Also, during the repair, antifreeze got on the pulleys..I cleaned them all around with generous spray of brake cleaner..they look clean.

Ford - F150 :: 1997 - Loud Squeal When Wheels Are Turned

1997 Ford F150, 6cyl, 138K miles. The truck has a loud squeal when the wheels are turned. This occurs when it's stopped or at low speeds (can't really tell if it's happening at other speeds ?). A friend who's a mechanic, upon hearing the noise, said he thought it was either tie rods or ball joints. I replaced the tie rods (original ones) and the squeal remains. Is there any definitive way to determine if indeed the ball joints are causing this noise ? When I posted before, someone suggested I may have a bad serpentine belt pulley, but the noise seems to be coming from the front end, and not under the hood.

Elantra XD (2001-06) :: Power Steering Squeal When Turned The Wheel To Full Lock

I have an 02 Elantra GT. I was dropping off a friend who knows cars and went to turn around, turned the wheel to full lock to make the turn and heard a squeal. I asked my friend what it was and he said it was the P/S and I just needed to add some P/S fluid. I got some fluid and sure enough when I went to fill up the reservoir it was below to MIN line, not too much below but still below it. I filled up the fluid and didn't hear the problem for the rest of the day but this morning I heard the same noise when I was leaving for work. I figured the fluid had to work its way though but am not sure if there is something else I should check or do.

Toyota - 4Runner :: Brake Pads Squeal When Pull Out Of Driveway

2014 4Runner SR5, 4k miles... It is sporadic, but here in the Midwest the weather is frigid. Is it normal for brand new pads to squeal right when I pull out of my driveway? It goes away, but I never had this with any other vehicle.

Toyota - Sienna :: Mechanical Whine / Squeal And Slips For A Second When Braking

I keep coming up with unusual issues with my can. Ok, so I just had to replace brakes and rotors on the front. Now when I brake, it makes a mechanical whine/squeal and slips for a second. (Randomly, not evertime) The noise seems to come from peddle. It's not a grinding noise like you would hear with low pads or rotor, or even caliper seizing up. I'm hoping nothing serious. Possibly bad abs pump??

Toyota - Tacoma :: Squeal Noise Only When Weather Is Cold And Truck Is Coasting

The truck has 230,000 miles and has a squeal that sounds like a belt but it's not. I have put the truck in neutral coasted with the engine off and the noise is still there. The noise only happens when the weather is cold and only when the truck is coasting. Under acceleration the sound goes away.

Prius (2004-09) :: Tie Rod Came Apart And Tire Turned Sideways

Yesterday the passenger side tie rod came apart on my 2005 Prius while I was pulling out of a parking lot and my tire turned sideways. It looked like it unthreaded itself. Lucky I wasn't on a freeway.

Prius (2004-09) :: Beeps After Being Turned Off Then Won't Start

I have a 2005 Prius with 64k miles, I bought used from a Toyota dealership, Toyota certified. It was purchased in Nov of 2009. In Nov of 2010, I moved the car onto the grass in my yard to make room for guests in the driveway. It was fairly cold out, but I don't think below freezing.

The battery was at all blue bars, with only the top two green ones not charged.

After I moved the car I turned it off and opened the door to get out. The car started beeping at me as if I had left the key in. However I had the key in my hand. I put the key back in, started, turned it off, took the key out and opened the door and the car started beeping at me. (identical to the sound when you leave the key in)

At the time I reasoned that it must have always done that and went back inside.

Prius (2004-09) :: Headlight Came On Then Both Faded And Turned Off

I drive a 2007 Prius - about 185k miles on it and purchased it used a few years ago. It's needed minor maintenance to it but overall it's served me well.

I hopped in my car this evening and went to turn on the headlights. After turning the knob, the lights came on - then both faded and turned off. These are halogen bulbs. Here's what I have tested - I don't have light in my driveway...

Prius (2004-09) :: Cruise Control Will Not Set When Turned On

My Prius is a 2009 with 30,000 miles.

Have just begun to have an intermittent problem with the cruise control (has happened twice in past month -- never happened before).

Turn cruise control on, but it will not set. Turning off cruise control and turning it back on didn't solve the problem. However, stopping and turning the vehicle completely off and turning it back on did solve the problem. The second time this occurred (this morning), the engine sounded like it was revving and seemed somewhat sluggish (not what you'd expect if the engine was revving). Not revving real fast, but noticeable.

Prius (2004-09) :: Inside Beep When Car Parked And Turned Off

The car was locked and parked. But the beep you also have when the seatbelt reminder is on when driving was beeping ( at that same speed really fast beeping when you do not put your seatbelt on after a while it starts to beep really fast ). I unlocked the car and open the door and it kept beeping... now of course I can hear it even better.. it was indeed the inside beep.... I closed the door and wanted to lock the door again but before i could press the button it locked itself.... I opened and locked the car again.. after a few seconds it stopped.....

Prius (2004-09) :: Engine / Red Car And Triangle Lights Turned On

Bought my daughter a used 05 prius. So far had had to repair the MFD, ac blower, 12v battery.

The engine light, red car light, the triangle light turned on. We replaced the 12v battery since we didn't know if it had ever been replaced. Drive the car for about 5 minutes, then all the red lights reappeared followed by not being able to accelerate. Immediately drove back home. First looked up the acceleration problem and it says to check engine coolant levels.

Low and behold the reservoir was empty. Purchased some, added it and drove around the neighborhood. The acceleration problem gone! Engine lights gone! Just as I am getting home, the dash lights disappear and the engine light only is lit, and red car on MFD. I drove it to our mechanic for error codes. It drove perfectly. As i go to turn off car, it wont turn off. It took another 5 minutes of power button holding, brake release and parking holding. It finally turns off.

Prius (2004-09) :: Keeping Engine Lubricated When It Is Turned Off

Does the engine turn on and off frequently lead to a lower engine life? I have always heard that the biggest wear on an engine happens when it is turned on. If the oil is draining from the Prius engine each time stops it seems like there would be a lot of engine wear.

Does the Prius (2010) engine have some way of keeping the engine lubricated when it is turned off?

Prius (2004-09) :: Buzzing Noise From Under The Hood When AC First Turned On

On our 2008 (26,000 miles), I've started to notice a "buzzing" noise (best way to describe it) from under the hood when the air conditioner is first turned on. Never noticed it before, but that doesn't mean it wasn't there.

If I drive the car with the ac on, then park the car for 30 minutes or so, it seems to not occur when restarting the car and the ac. A little vague, I know. Sound normal to you?
