chirping noise while heater is on?

just started doing it this morning on my way to work. i had the heater on the 2nd power notch going to the face & floor setting. turned it to just the floor & a few minutes later i started hearing a chirp chirp chirp noise. so i turned the heater off, it quit. waited about 5 minutes & turned it back on, started doing it again. i checked in the floor board to make sure the heater core wasnt leaking, didnt find any moisture! a guy at work think it may be the fan slipping for the heater! any info, any1 replaced this, any help would be much appreciated! thanks in advance!

 

Mine started last week. If you are still in the warranty period there is a TSB to fix it... I am out of mine.

 

My 2009 tacoma does it and my dads 2008 tacoma does to. Its annoying as piss. Id like to know how to fix this problem too.

 

Whats the tsb number?

 

Every Toyota I have owned did this! It's annoying as hell!

 

sounds like its your blower motor...my 2010 did this in the lower settings and it really got annoying after awile. it seems to be a common issue...i took it to the dealer and they swapped in a new one (under warrenty)... problem solved. hope this helps

 

hmm, my warranty is long gone. ive had this truck for 6 yrs, never have heard this noise before. yes it is annoying. i may just try & replace the blower motor, i will lookinto it. thanks for ya'lls responses!

Don't know if you saw it yet, but that might help. I have a very slight clicking (maybe a chirp) noise from mine as well. Let me know if anything changes if you decide to clean and regrease?

 

I have a 2010 Tacoma with 5000 miles on it, mine started making the same noise around 3000 miles. Its at the shop today getting fixed. They tried telling me I would have to pay a $97 diagnostic fee if they found a nest in the motor or determined it wasn't covered under warenty.

WHAT PART OF ONLY 5000 MILES ON THE A NEW TRUCK DO THEY NOT UNDERSTAND.​

Going to pick the truck up this afternoon, we'll see how much yelling it take for me to walk out without paying anything.

 

Remove and inspect, lube or replace. I think they are about 50 bucks. My 01 just started doing this in time for the cold snap

 

Usually the bearing in the blower motor that makes the noise. The only fix for most of them is replacing blower motor/fan (one piece). There is tsb for 2nd gens, which has 2 parts depending on yr and VIN. One you replace the motor and the other has a noise kit you are suppose to install around the fan part of the blower.

There is the chance of having something in the fan part and its easy to drop down so I'd start with that.

 

2001, same chirping. Now its quiet and I can't hear it run!!!

Remove blower motor,
Remove squirel cage, not that easy, pry off with two screwdrivers and a helper, DONT USE A HAMMER ON THE SHAFT, you will pop off a snap ring under the cap,
Pry off the cap under the squirel cage and saturate the felt with 3 in 1 oil,
Carefully pull the motor out of the plastic housing,
again, saturate the felt with 3 in 1 oil,
reassemble.

You might be able to oil the lower felt without pulling the motor out of the plastic housing, there is a hatch you can remove from the plastic housing and with that off, you should be able to get oil to the felt.
Don't worry about getting oil in and around the motor. Just don't get any oil on the armature/brushes.
You may be able to oil both felts with the hatch off, if you have a 3"-4" hypodermic needle and oil.

 

thanks for the info guys, will look into fixing it soon!

 

I have this problem, it sounds like it's coming straight out of the vents and comes on with the A/C also. Should I look at the blower motor first?

 

Mine has been doing this as well, time to take a look.

I know its been mentioned but change or clean/oil your blower motor. My jeep did this and its annoying. Sometimes you can take out your blower and clean it out. Mine had leaves and all sorts of dirt so it might just be dusty and squealing. Im not sure how hard they are to take out of a tacoma but my jeep took all of 5 minutes.


From experience though usually when they start making that sound there about to go out but its a easy fix, The the blower motors are around 60 bucks I believe. Clean it out first you might save it some life.
