Toyota - Avalon :: 2008 - Slow A/C Fan Speed
Jul 22, 2014
My 2008 Avalon A/C fan speed periodically won't run at the highest speed. When I take it off of "auto", I can step up the fan speed and see the segments on the display light up with each increase in speed. Each segment lights up (they are in a oval shape) indicating that it should be at the highest speed, but it just doesn't seem to blow as hard as it used to.
I think this fan motor is controlled by a PWM controller rather than resistors. Is that correct and where I could find the PWM controller? My thought was that if it was not too expensive I would change that out first. If the fan works, could there be a problem with the fan motor?

Ok, here is what happens to my car:
The engine wobbles when idling or at very low speed - some times the engine shuts down in stop and go traffic (very dangerous). Doesn't pick up speed when i try to accelerate from a stop position - the engine revs up and then the car lurches forward (suddenly) as the transmission seems to engage. The same happen when i slow down to almost very low speed and then tries to speed up. I also hear a kind of thud (transmission most probably).
The CEL is ON and some time blinks.
My OBD is showing the following codes: P0171 P0172 P1150 P0300 P0302 P0304 and P0306

My '05 Highlander transmission seems to be geared wrong. When I slow down the car seems to slip into a higher gear and speed up. It is worse when the air conditioning is on.

I have a 2001 Toyota Echo which developed severe vibration feedback to the steering wheel when the car was driven at low speed or stopped at a traffic sign or signal.
I took the car to the Toyota dealer and they checked the brakes, replaced the front rotors. They also checked the fuel pump and other engine components. The spark plugs and PCV vale were replaced, as well as the crank seal.
When I left the garage, the vibration reappeared after driving about five minutes. I immediately went back to the garage and waited while the mechanic checked the car. He came to the waiting room and said I would not believe what they found. I went to the garage with him and the hood on the car was raised. He started the car and there was no unusual vibration.
He closed the hood and the vibration started again. The problem was that the underhood reinforcement panel had come unwelded (or unglued) and it was vibrating. A mechanic came from the body shop and put a sealer/filler at the loose spots, we let the car sit for a while, the mechanic said the sealer/filler would expand to close the gap, and I drove the car home. The vibration had stopped.

I recently (<90 days, < 3K miles) had inner & outer tie rods replaced on the right side; they were rusted from when I lived in PA and had some play in them. Now I'm hearing a funny sound at low speeds (like when parking) that's just like a stick getting caught in the wheel well ("thunk") that seems to be coming from the same spot, but I can't seem to replicate it let alone hear it at the shop. This is a 2001 Camry LE 2.2L I4 with 97K mostly highway miles and one winter on salt/snow.

On my 2006 Camry, my ABS comes on intermittently when braking (~5% of the time) and the speed is very slow (5 mph or less). Exact speed is hard to say. I think one of the ABS sensors is misreading. No ABS fault light on dash.I have an explanation of how to check the sensors for AC voltage when spinning the wheel using a DVM.
1. Without a lift can I check this under the hood instead of at the wheel? Possibly at the plug into the ABS module.
2. Someone else on another thread mentioned that their dealership hooked in a monitor and drove around.
When I asked my dealership how they would diagnose this, they said they would do the same check as I mentioned above (#1). This would be expensive and since it is intermittent, they might not see anything. Do this monitor exists and what it is called?

I have a 2003 Toyota Camry. About 10 months ago, when I get a transmission fluid change, the mechanic told me that my power steering fluid is dirty. A few month later, in the cold winter month, my steering wheel make loud screeching noise when the engine is cold only. The mechanic told me that I have a small power steering leak. But since I don't see the power steering fluid level goes down and the mechanic say I don't have to fix it now, I didn't do anything about it.
About a month ago, there is a squeaking noise come from my steering wheel every time I drive very slowly out of (or into) my driveway and turning the wheel. Now I heard the noise when I drive slowly (10 mph) and turning the wheel too. So what is the problem that cause the noise when I turn the wheel at slow speed? I only drive about 5k miles a year. Is it safe if I just continue to ignore the problem?
Also, the color of my current power steering fluid is amber, but a little dark. Which power steering fluid should I buy?

My Honda has a pop or clunk when braking at low speeds( below 5mph) just before coming to a stop. It will pop as I start forward again (below 5mph). It only occurs when the outside temperature is above 90-95 degrees and after driving for 10-15 minutes. Dealership has looked at it twice and has not found any issue. I've changed brake pads and rotors as well as lubricated everything - didn't work. Brake performance, handling, etc isn't affected. It's highly annoying and makes me worry that something will eventually fail.

I have a clunk/rattle in the drivers side front end when I go over a small bump at a slow speed. The dealer said it was the struts - they replaced them along with the upper support thing. Noise still there, next they said it was a worn motor mount - noise still there --

Looking at a truck at a dealership. 04 F150 Lariat 5.4 3v? 2wd SuperCrew 148k miles. Bone stock besides the bedliner.
Truck is pretty nice besides these 4 things. Kind of a shudder when taking off from a stop or a very slow speed. Adjustable pedals don't work.
New brakes, but possibly the rears are dragging a bit. Was able to turn them in neutral and the rear on jacks. Extra, guessing because of the newer looking battery, some systems lack data from the OBD2
I'm mainly concerned about the shudder from a complete stop/1-2mph. At the dealer, to leave the lot, the driveway was elevated. I think it showed very well climbing that hill. As it was noticed and played with the gas a bit. Otherwise, you stomp the gas, it may shudder for a second or two, (3-5 times?) once it hits about 3000 rpm in 1st, its fine. Only ever seemed to do it in 1st and never any other gear, never on any gear changes.
We lifted the rear end up on a jack and fiddled around. Put it in neutral and spun the wheels, tried to mess with the drive shaft... According to dad, who was looking at it with me said it was fine and that it's normal to have a little bit of slop, but I didn't notice any real slop myself, tried to push on the driveshaft on the transmission side and I think it may have moved a bit but it didn't feel loose or clang or anything. Although I didn't get to push on it too hard because he was rotating the driveshaft at the time.
I assume new fluids in engine and trans. My dad said something about old oil marks on the transmission pan area or something. Both to the fill line.
One thing that I wonder about is how long this truck has been sitting. I wonder about the differential clutches. I'm not that sure what it really has for the rear end. But google had mention of clutch packs in the rear. I wonder if because it's been sitting that the oil has settled out of the clutches or something. There was a mess of silicon on the rear diff cap area. Couldn't tell if it was new or not. I think we put 10-20 miles on it at least and only looked under it for maybe a half hour... Still did the clunk/shudder at a start from a stop, when we returned it.
So, what could be causing this clunk/chatter when talking off from a stop/1-2mph roll?
Axle wrap?
Differential Clutches?
Differential?
Driveshaft?
Transmission?

Does the 2008 Avalon 17" wheels fit on a 2011 Toyota Camry SE V6? I called the dealer and he could tell me unless I had both VIN Numbers.

Just purchased a used 2008 Avalon from my uncle. The car hasn't been driven much the past few years. I'm driving across country right now from Chicago to Seattle. We are about half way through the trip and I notice that the engine has what appears to be water dripping out near the center of it. I have checked the fluid levels and everything appears to be normal. The coolient is full. I have read that it could be the AC dripping water, however, it is a relatively cool day 45 degrees F at the moment and we just had the heat on in the car. Is this something I should be concerned about?

Just like the tittle says. My 2011 ISF with 56k miles on it is making a Clunking noise when pulling out of a parking spot or just anytime I fully steer to the left side and begin to move. If I try it in reverse it doesn't matter if I turn the steering wheel fully to left or right it makes the same noise as I begin to move at slow speed. It almost feels like something is pushing the front wheels out. During normal driving I don't feel anything at all, just as steady as solid the car can be.
Is there any common issues with ISF with premature wear of ball joints, cv joint, sway bar bushings or hub bearing?

2008 Highlander - super slow coolant leak. Dealer can't find it via pressure test. Never trips sensor, but after 6 months or so, the heater doesn't work well unless turning to the left. Has happened since new, but now Just out of warranty. Dealer has recorded two pressure tests and leak, but I'm wondering what to do.

I have a new to me 2005 F150 SuperCab Lariat 4x4 with 155,000 miles on it. About a week ago I replaced the from passenger hub assembly and half shaft (torn boot). When doing that, I noticed that the IWE actuator was not working right (would not compress evenly). When taking that off, there was a bunch of rust that came out of the vacuum line ports. It started moving freely after cleaning all of that out that I could (I will be replacing it soon). I assembled everything back together and all seemed OK mechanically.
I also scanned the truck and saw the code for a bad IWE solenoid so that is being replaced tonight. I also have not checked the drivers side yet.
So...now that I have done all of that, the truck started occasionally bucking/shuddering when I slow down from highway speed to about 30mph and lightly accelerate again. It does not do it every time though. There is no grinding/whining noises either. Could this be caused by the IWE system somehow? Maybe slowing losing vacuum and having one engage and the other disengaged?

My wife's car is a 2006 2.0T Passat. It has been very slow to blow cool air on starting. Once you are moving at highway speeds it cools fine, but then blows hot air when you slow or come to a stop.
I have taken the car to a mechanic who purged and refilled the coolant. This did not fix the problem. Upon checking with the mechanic, we noticed that both the primary and aux. cooling fans start and stop at the same time, and only would come on when I would rev the engine up some (around 2000 rpm).
I have talked with this mechanic and one more. Both are certified master mechanics, but neither specializes in VW. They believe it may be the high pressure side switch or the compressor itself.

My Avalon tranny slips a bit sometimes when going slow around corners and then accelerating. Also, it seems to downshift itself when going down an incline at 45 or 50 mph. When entering traffic on a freeway ramp and getting into passing gear, it seems to slip quite a bit before catching and taking off. Is all this normal? 55,000 on the car so soon to go out of warranty. BTW, can the dealer check this out with diagnostic equipment as I would bet they couldn't recreate the problem test driving....never fails!

My 97 Saturn SC1 dies as I slow to stop. It will restart but the RPM goes very high for a little while before it drops back down to normal. What do I need to do to fix it?

I've gotten it a couple of times lately while turning at slow speed. The first guess is always the CV joint/boot - but wouldn't that be multiple pops?

At any speed my car likes to slow down a bit then go back up to speed... feels like little mini lurches. Why... dirty fuel injectors?
