Thread: Blend Door Actuator Replacement

also can someone take a pipc of the interior fuse block with the HVAC Control fuse (20a) should there be two pins the fuse plugs into. mine only has one terminal the fuse plugs into. could this be the reason im not getting mode actuator movement? but my HVAC Module has display and moves the temp actuators.

you could test the plugs to the actuators for power.

inside is just a bunch of gears, a big one and a smaller one. looks kinda like a gear reduction set up.

you can turn the actuator with a fat screw driver, put it in the hole and turn it. ( slowly) no need to take it apart to calibrate anything. it either works or dont. like i said, i plugged my used ones in and worked the controls hot to cold to make sure it worked. they only move a small amount. and slowly.

after you take your off, make sure the little knob it turns turns freely too.

and if you pull that fuse if your climate control goes black, the fuse is working right.

got ya. not sure if i have a bad one in my trunk still, if i do ill pop it open and take a pic for ya tomorrow.

thanks!

sh it, i forgot to get that pic for ya. i got stuck working in the heat for a few days. never even looked for it lol sorry.

my car runs cooler with the a/c on as both fans are on. so when the ac is turned on, both fans come on full time?

i went over a year or so with no actuators, the driver side would walk back on its own, so i set the knob to cold, and made the actuator match, then just laid it on the knob, no screws at all, it held it in place.

this was also good for winter time, as full hot is no good but a touch over 1/2 way worked fine for me, once again the actuator held the knob in position.

yup both fans are blowing full speed.

Right now I'm having an issue with my 02' GP GT. The passenger side blows cold air on AC but the driver's side blows hot. Does anyone know the part number for that Actuator Motor. I'm assuming it needs to be replaced. Thanks. I'm tired of driving with the driver's side vents shut and turning all the passenger side vents my direction. It's getting too hot these days for that kind of nonsense. I'd rather sweat my azz off for one day repairing it.

If you need an actuator, RockAuto has the best price by far.

Good luck!

Thanks! I actually have a recharge system in the trunk right now. I'll dump it in when I get home to see what happens. I will say that the passenger side doesn't blow as cold as my 86' Olds did so you may be right. I still don't know how to differentiate between Auto AC and Manual AC systems??

automatic AC or manual? auto is 604-106 manual is 604-107

Not to sound dumb, but I am. How do I tell if it's an Auto System or a Manual one??

you can pop the d/s actuator off and then turn the knob by hand, if you can make it blow cold manually the actuator is bad.

if its still warm, the system is low for sure. but you got the a/c gauges so you can also test the line pressures.

and its been f ing hot here the last few days.

not sure what the difference its either, you got lkq parts right down the road from you, go ask them for a used one. LKQ Hunts Point Auto Parts

Thanks Scotty! I'm so glad my work station is directly across from the AC Unit here at the lumber yard. I'll install the freon first and if it's still hot I'll try and manually close the door. I saw only one video from a 98' Chevy Something, and it didn't look so bad to reach from under the driver's side dash.

first post of this thread is the how too to change them. drivers side is a bit tight. but very doable. i wear size 3 x gloves, so i got large hands, yes i bled a little, but i got em in and out. more then once sadly lol

Well, thanks Scotty. I dodged a bullet with this one. I got home from work and attached the can of AC Pro, set the AC to Max, and let her rip. It was definitely low of juice. After 5 minutes the can was empty and all the vents were now blowing COLD ICY AIR!!! Whew! No taking apart the dash for me thank God! Also, I noticed as you had said, my temp gauge went down with the AC on Max too. Thanks everyone for all the help. No more sweating for me in the GP!

I guess I spoke too soon! I get downstairs this morning and hit the AC Control and the passenger side is ice cold but the driver's is still running warmer. Big difference though from before, just not as cold as the other side. So I guess I'll be under the dash this weekend!

Yep, I set the ambient temp gauge and it was at the proper charge, but at the "low end" of the spectrum. The can was empty at that point. At the instant I finished, both sides were blowing cold with the passenger side just a smidgen colder. I never sat for an extended period of time though. I just shut it off and went upstairs. I may need another can to get to the higher end of the scale.

i think it has a leak somewhere. if it worked, now dont work, it leaked out.
