Poor Heat/Poor AC

My father's 2000 Camry (2.2L) has heat & AC, but you need to put the vent on 3 or 4 to feel it.

car has no issues warming up, no overheating, no leaks...just poor heat & AC distribution, I was think t-stat, as the car as 164k and he said it has yet to have been changed.

Ideas? Thanks

G-morning Fuzzy and welcome!

That's not much to go on.

Does the heater blow air on all settings?
Does it moving the slider to outside air improve flow?

Does the AC compressor engauge when turned on? Theres a whole lot of details missing.

Can you describe what does work?

Thank you sir.

Heat & AC blow very little if anything on the 1st 2 vent setting, on 3 & 4 they operate similar to how 1 & 2 should operate

With the outside air it improves only when on the hwy, city driving there is no difference

The AC compressor does engage and blow cold air, just not at the power it should while at the vent settings

Blower motor maybe? Do these cars even have blowers?

Did a bit of digging, these do have blower motors and supposedly the blower motor resistors are a common Toyota problem, I think I may start with that, think they're like $30 @ the dealer and located under the passengerr side dash (glove box area)

Anyone have any other input before I run off in this direction? Thanks for the quick replies

IMO the resistor is only applicable for low settings. High should be 12v direct.

Any chance the car has small four legged passengers taking up residence?

Sounds like either the motor or blockage from something else.

Remove the lower cover passanger side and the blower has pretty easy access. Pulling it will resolve the habbitate issue and check that the motor spins freely. It could have dry bearings limiting it RPM.

You are correct in that at the low settings the air distributed is the onyl think affected, I think I may have misspoke in one of my posts about the high air being bad as well.

In terms of 4legged creatures, the area does have some around, but I've never seen any evidence of them in/around the car.

If the blower in fact does not spin freely, is it something where I could apply some type of grease, to re-lube it?

Thanks

Sorry, can't help ya on that one. I mean I've always found a way but I've never had to deal w/this so I can't say.

If you get it out the blower cage end of the motor is guaranteed access because of the shaft which hold the cage. The other end may be covered tho.

In this case, gravity and mobil 1 sythetic would be my choice. Get the lube to the shaft and let gravity take it to the bushing. Spin it by hand and hit 4 times over an hour to see if it frees up.

No problem, thanks for the guidance. I was just asking about the blower as a worst case type of thing, hopefully it's the resistor, which from input and other searches that seems to be the issue

Pull the blower motor and inspect it. Also...inspect the evaporator fer dirt/clogging. I used my point and shoot camera to git piccies to look at mine...

That rivals some farm equipment I've seen! Q? What environment made that so nasty? Definately not a simple "in car cleaning" to recover from that!

Perhaps corrosion took over ate a hole in it too boot, thus compressor oil is present too! Wicked!

Well...I made my own thread some time ago.

The T-100 was a former work truck...it's been in this condition ever since I got it about a year ago. As you can tell...I've been experimenting with various things to make it a little better. The foam wrap has been my best return on investment so far. I likes it cold in the truck!
