Prius (2004-09) :: 2006 - A/C Blower Speed Slows Down When Set To High After Running For A While?
Sep 4, 2015
I have a 2006 Prius and lately, the fan will stop blowing hard on long drives on hot days when the fan is set to High. This happened on a 3 hour trip on the interstate and again when I was driving some back road for about 2 hours. The first time, I noticed the cabin temp was getting hotter so I went to switch the fan speed higher and noticed it was already on high. It was not set to Auto.
When I got home, I let the car cool down for about 30 minutes and when I turned on the car, the AC was blowing full speed and was getting cold like normal. When the fan speed slowed down on its own on the interstate, it was probably blowing at a speed similar to what the fan would normally blow if set to the middle position or maybe even below that. Why the fan would slow down on its own when set on high.
I also just checked the temperature coming from the vent after running the AC on LO temp for about 10 minutes. It was reading 50 degrees with a digital meat thermometer and 46 degrees with an infrared thermometer. So, when the car is cool, the AC seems to be working fine. Just wondering about the fan speed and the fact that the car gets really warm when it slows down on its own.

I just purchased a 2001 Dodge Durango 4wd with 140,xxx miles on it. My issue is that whenever I accelerate it hesistates and if I am going at a high speed like on the interstate or expressway it sometimes slows down (drastically) if I'm going uphill. What can be causing this?

Whether in heat or AC mode and any dial position, I'm not getting nearly enough air blowing out of the vents to cool or heat the cabin in a timely manner. The fan switch is working in all positions but I have to use high speed all the time to get enough air to defrost the windshield. I've also noticed that when defrost is selected, air only comes out on the inside part of the vents, not the outside. Is there a cabin filter on this truck, I've checked auto parts stores and they don't list anything for it.

For those of you that own both a TCH and a 2010 Prius I have a question for you. My commute is only 6-7 miles to work and currently I am getting approximate 45mpg displayed on the mfd. I think I read somewhere that the display calculations may be a little high but all in all I am very happy with my mpg. I am considering trading my 09 TCH for a 2011 or possibly 2010 Prius if the price is right. Anyway If I accelerate my 09 TCH to approximately 41 mph and take my foot off the accelerator, when the car speed slows to about 38 to 37 mph the engine will shut down. I can now lightly push the accelerator to drive along just using the battery. If on a flat road or a slight down hill grade I can even pick up speed and get to about 41 mph before the engine starts back up. My question is how does the Prius work the same way? What are the speeds for the Prius?

I normally run my climate control in manual mode, and I notice that my blower doesn't always run at a constant speed. I know that if you use the Auto setting the fan will change speeds, but I didn't think it should do that if you are using a manual setting. Is that right?
I was thinking I would make an appointment with the dealer to check it out. But didn't want to do that if this is normal behaviour.

My girlfriends B6's blower fan as of tonight only has the speed of 4 (max speed). What to do to fix it etc...?
Here is a pic of the car......

Blower only works on high speed. From what I have read the problem is either the switch or the motor resistor. I am leaning toward the resistor which is behind the glove box. Where can I find directions for removing the Glove box?

I recently bought a 96 ranger.I noticed the fan did not work but for high. I search the internet and found how to remove it and discovered a mouse nest(village) which basically took over the housing where the evaportor core,blower motor resides. I bought a chilton but cannot remove the housing around the core so I cleaned it the best I could(air compressor and vacuum and disinfectant)...
I had to buy a new blower motor and resistor. However, I cannot find the hose that attached to the blower motor?-mouse had chewed a hole in the one- I've looked and found serveral differents names for it but seems I cannot find it at my local parts store.
My question is- is this intake hose? vent hose? I'm guessing I will have to go to dealer or, if I know the name I can look it up in a salvage yard?

When I turn on my fan for the AC or vent or heat, it works just fine on the first and second settings. When I move the fan speed to the third and last speed, I hear this sound that sounds like the blower fan is hitting something. I turn the speed back to the lower two settings and noise goes away. Sometimes I turn it back to the higher settings and the noise actually will go away but most of the time the noise is there.
I pulled the blower motor out yesterday and set it to where I can turn it on while out of the compartment and I didn't really notice a noise. I wonder if the noise is there but I am just not hearing it since it is not enclosed in the compartment? I also noticed there is a crack in the fan where it mounts to the shaft starting at the shaft and extending out one direction and also 180 degrees the other direction. Thoughts on if the motor is bad or just the fan? Or even something else that I may not be seeing?

I replaced the blower motor resistor on a 2010 F150 with dual climate control where the blower was stuck on high.
After replacing the resistor, now the lower speeds work fine, but when placed on high speed, the fan completely shuts down. Replace with the old resistor, and it only runs on high.
How to proceed, or what else might be the problem?

I am struggling with it, and need to get it done - by myself, as I can't afford a service job. I am handy, and comfortable doing it, But I am confused about how to get into the blower housing.

I am a new buyer' bought my prius 2008 about a week ago. the is something i cant understand, when a the engine runs at idle speed, the fuel consumption monitor shows 99.9 km/liter ! ! ! and it's also calculated at the average... is it something i should worry about ?

I've got an '04 Pkg IX with about 68k miles on it.
I've noticed that at speeds of greater than 60mph there is a distinct ticking noise (like the sound a bicycle makes when you turn the wheel "tick tick tick"). The noise is coming from the front end, sounds like near the passenger area.
The minute you drop down to speeds of around 50 or less it goes away.
I'm probably going to have to take it in to the dealer since I've already had an indy look at it.

How the radiator fan goes into high speed? My 2006 Prius A/C works great as long as I am moving. But when stopped in traffic or at a light, the radiator fan does not go into high speed. So the A/C shuts off until I can get cool air back through the condenser.
I replaced the two fan relays, and when I do the fans run into high speed for a moment, then back to slow speed. Is there a temperature sending unit in the Prius I can replace?

The blower on my 06 sonata is only working in high speed, before this it was going haywire automatically increasing and decreasing in speed. Funny thing was that it was blowing air even after i switched off HVAC.
When I got home i removed the blower resistor to check it because the symptoms were pointing to the blown resistor but it doesn't look burned to me. What else could it be?

Started yesterday. Dry road. Brand new Perrelli P4s . at about 60-65 traction control comes on and car starts doing the "surging". I had the same tires on it up to this point so except for being new,no difference.

I have google it looked all over was told it was under the hood next to the fan even shown a photo when I went under the hood right were the resistor was in the photo there was a long black box about 4 inches long and 2 inches wide. looked nothing like the photo.
So I went back on line and read that its above the passengers feet you take a few screws off after you take the glove box off and it should be there. Well after taking 8 screws off I find nothing but a coil behind there. Nothing that looked like a resistor.

Went to have an oil change....service rep came in with my cabin air filter and said it needed to be replaced, I told him "later" as they charge too much for a simple filter.
Two days later I had the need to run my blower on high and it vibrated rather loudly.. I tried different positions on the vent switch but nothing worked.. then it came to mind the Jiffy lube incident. I went in and pulled the cabin air filter out and saw nothing wrong there. Upon further inspection I found a piece of an acorn in the blower wheel.
Moral of this story...if you changes cabin air filter, be sure to check for any debris that may fall off the old filter into the blower wheel when it is removed.

When I accelerate A/C is fine but when I go to brake (RPMs go down and car downshifts) my A/C blower power goes from high to low and then fixes itself and if I brake again same thing but it does it intermittently. What it could be?
