Josh S: I have a 1991 GMC, and my buddy a 1989 GMC. Both have a distinct tapping sound on the passenger side. Sounds like plastic plunking on plastic. Would this be the solution to our problems?
Billy Holmes: almost same problem the AC pulsates but dose work good , and only when put in the floor position. think it the same problem?
Kevin goodman: 99 chevy suburban 2500. windshield vents doesn't work and it leaves my suburban foggy???
CS Ham: Same, here Followed this to the tee and fixed my problem in just a few minutes. Thanks for this video. I have a 98 Tahoe that did the same thing earlier this week. I had no idea what was wrong and considered taking it to the dealer until I saw this. Thanks Man.
froggy: My 02 Suburban has a similar "issue". When I direct the flow to feet/floor it's all fine. If I direct the flow to dash or dash PLUS floor I can hear a door clunk noise as if the door is "trying" to move & moves for a while then falls back out of position.
Does that sound like the same issue?
Mine is NOT dual climate control or the electronic control where you set temp & it does the rest. It is almost identical to yours only 2002.
Joe M: Really helpful and well explained The mode door on my '98 Silverado has been slowing going bye-bye for a couple of years and I wasn't sure what was causing the issue. Thanks to your video, I know what the problem is and how to make repairs with relative ease. And, your price information was right on-$39 at a local auto parts dealer!
Appreciate the well-done tutorial! :-)
Lost Soul: Tyler: 1997 GMC Silverado, no air thru the dash vents when turned on HIGH. Replace the servo in this video? Thanks!!
Lane Rourke: 2000 k3500. Ac doesn't blow out vents powerful. Any idea which one of the 3 would cause that?

Planted Tank Empire: My driver side defrost doesnt have air flow but the passenger side does. Any suggestion thoughts funny looks?
Christi Alford: thank you sir same issue fixin to tackle it as its time for the heater
david smith: my 02 Silverado will go from defrost to vent as im driving and will get stuck on vent for a few days and will never go to floor any suggestions
T4nkc0mm4nd3r: Thanks for the video! my mode door motor has died I'm pretty sure so I'll be doing this shortly
Gino8451: hey tyler i have a 2000 GMC and my air con works but after a while it stops blowing cold air then i shut it down and turn it on again and it works what do you think it is should i change the passenger modulator.
keithen bishop: I've got this same problem. Like sometimes it'll work but if it doesn't I just hit the control panel and the a/c comes on. The only thing I'm scared of is in the winter time. If I switch it to heat it stays on heat full blast
John Artuso: I get hot air coming into the floor area of my 97 GMC even though I want cold air only .... I have replaced the control module and now I need to replace servos ? .. but which one isolates the heater core from the cold air air , with my luck it'll be the top one ..lol
manuel martinez: thanks!
i've the same problem with my truck
Bobby G Pitts: THANKS MAN!! Sure help me find which one was what.
axegrinder0308: Ok just so I got this straight....So it's perfectly OK to test these motors when they are not hooked to the door?
