How many blowers in a 123?

Okay, hold the jokes here.

Is there an individual blower for the AC and an individual blower for the heat in a 1982 300D, or is there one blower for both?

Thanks,

Pete.

One blower, one motor, no laughs.

I think one motor only. But if it's a Jeep Grand Wagoneer, it may be anywhere from a minimum of two to a maximum of two every year...

Good luck.

Currently in mine, there's exactly zero blowers. Man, it's cold in the mornings. I took it out to replace brushes, only to find the whole thing is just bound. Waste of time, so now I'm looking for a replacement. I've noticed, the price on this thing starts to seem more reasonable as it gets colder.

I opted for the aftermarket one you can get on ebay for around $160 vs. $320 for the OEM....its good....works fine, but they are cheaper made (the fan wheel especially its not a solid piece like the OEM, the motor is fine/good) and it tends to vibrate on high (full power) on levels 1-5 its quiet and doesn't vibrate anything. I run mine on level 5 most of the time, and 6 in defrost and the vibration is annoying but bearable (perfectly fine since it saved $180 )....hey at least it moves the air, and A LOT of it. My old one was fried/seized as well.

*Edit*

I looked at the $341 one from Behr on Fastlane, and it looks identical to mine, same blower wheel etc...mine was unmarked, so I have no idea what brand it was. I guess only the originals had the heavy solid plastic wheel. I'm glad I got mine for $160 though......2 years strong so far....use it constantly every day.

If you have ACC then there is at least one small one that draws air from the center dash past a temp sensor.....forget the exact name right now plus the main blower motor...

Well, right now I've got no air coming out (hot or cold), though I believe the heater and the air compressor still work. The previous owner replaced the ACC and refurbished the heater blower. Just want to make sure before I dive into it that there's only one non-working blower I need to deal with....now there's two?

With that description you are after the big one......you will see behind the glove box....the little one will effect temp regulation issues..

What was his description of "refurbish"...try a jumper wire direct to the battery to see if it works at all....if it doesn't the motor is at fault...if it does you have bigger problems to sort out.

Good point, I'll try a jumper wire to the batery.

He refurbished it by having it cleaned and the brushes replaced. Don't know much more than that.

Pete.

On the W123 there is no blower motor for the temperature sensor as you described. The W123 uses a foam and hard plastic tube that is attached to the temp sensor then goes to the blower motor casing to draw the air over the temp sensor by using the suction action of the blower motor.

So just one blower motor in a W123. As posted just above the passengers feet.

I know the W116 has an aspirator motor drawing air into that tube from the dash for the ACC...I never needed to look that closely at the W123 yet.
