I go to the dealer spares department when I have a problem like this and have them show me a picture of the vent system in the car and I point to the bit that I want. Saves a lot of time and energy when you can point to the bit As to how to replace it the break down will also show the area and you can see if there are clips or what to get the bit replaced.

SOURCE: There is no air flow

You need part GM Part number 89018675 or ACDelco 15-73596. The Mode Selector Actuator. What happens is the part is a CHEAP part POORLY designed and when it goes to turn the flaps inside the HVAC unit its the plastic gear slips instead of turning the flap!!!

Just to forward you you might want a deal to install this art for you unless your good at fixing your own vehicle, because you need SMALL sockets and a lot of patience to get this part in!!!

The part is ALMOST directly above the steering shaft for your steering wheel, so theres a lot you got to remove before you will even see them!!!

I only recommend you to have a dealer put this part in for you, unless you have your own service manual!!

Because there is 5 of these darn things and if you pick the wrong one you will have to do it all over again!!!

3 on the Drivers side and 2 on the Passengers side!!

But replacing this part SHOULD solve all your problems!! AS it did for me and i was having the same issues as you have described!!

SOURCE: air only blows out defroster vents

check the a/c doors, they may have jam, also if the system is non electric, check the vacuum line that runs to the a/c

I have a 1975 k5 blazer and it blows cold air it worked fine last year but now it only blows cold air even on the defrost setting what can the problem be and how can I fix it?


A vent flap actuator probably needs to be replaced. It's what moves your vent flaps from heat to A/C or to plain "vent air" when you change settings.

The discussion in the link includes vent flap actuators. Unfortunately, they also include the infamous no low speed fan problem too.

Cannot get any air from dash vents while defrost and floor vents work fine...

Your particular actuator will be a different one than they found.
They're all a absolute pain to get at because they can be well buried in the dash. I would start looking under the dash on the passenger side, that's where most of the air control is. Cannot get any air from dash vents while defrost and floor vents work fine...

What diverts air to defrost. Air comes out vents and floor. ac works and heat , but won't go up to dash vents. The flaps are working.


You just THINK the flaps are working, but apparently the top vent is not. These multiple flaps are controlled by vacuum and you have a line off to that particular flap. This means the flap won't open and the vacuum leak, whether you can hear it or not, is making you lose MPG also, though slight. The vacuum line could be cracked or disconnected from the flap or at the vacuum block on the back of the lever unit.

Jeep AC blows cold air at defrost and feet but not through vents


There is a flap that directs the air. the flap is controlled by a vacuum actuator. This is located inside the venting. The actuator is connected to little vacuum hoses that attach to the temperature control switch. Either the flap is stuck, or the actuator has gone bad.

Why is all the air blowing through the defrost vent only


Either the door that controls the flap that either sends the air through the defrost or the regular outlet is stuck or not working. Some of them work off of a cable and others work from vacuum. Not sure which the ford escort uses but usually you are able to hear the flap move when you go from defrost to regular cabin vent. Or possibly the air duct hose has come off that sends the air through the cabin. Good Luck and hope this helped a little.
