03 chevy trailblazer and my problem is that my ac only blows

Customer Question
HOT AIR! It was working...
03 chevy trailblazer and my problem is that my ac only blows HOT AIR! It was working fine and just went out. Blowers are working properly, properly charged with freon, compressor works, but it blows HOT at any setting I put it on
JA: Sometimes things that you think will be really complicated end up being easy to fix with Chevy. The Chevy Mechanic I'm going to connect you with knows all the tricks and shortcuts. Are you hoping to fix this yourself?
Customer: Yes & thx
JA: Great! What have you tried so far?
Customer: I had the low & high pressure side attended to. High psi side was HIGH and mechanic leveled it out to normal levels on both sides. Freon is in system, compressor and clutch working properly. I took passenger side floor panel/glove panel off and I didn't notice the motor turning on the actuator w/ac on. Could it be my flaps aren't closing or my climate control box gone bad?
JA: Is there anything else the Chevy Mechanic should be aware of about your Chevy?
Customer: Check engine light came on at the same time my ac stopped working. I had to have my catalytic converter changed, but ac is still blowing HOT!
JA: OK. To minimize me, please click the down arrow at the top right corner of this box. OK. To minimize me, please click the down arrow at the top right corner of this box. OK. Got it.

Yes, we had psi gauges set on high & low psi sides. Airlines were cold and yes, it's a dual zone.

Hi. Different expert here. Do you still need help with this? I see your other expert left the chat.
Ask Your Own Chevy Question
Customer reply replied 1 year ago
Yes, I do!
Chevy Mechanic: EricFromCT, ASE Certified Technician replied 1 year ago
Ok. If the temperature does not change at all it is most likely the blend door actuator. The other expert is correct that it is on the drivers side of the heater box. It is behind the instrument panel though. HAve you been able to at least get a visual on it yet?
Ask Your Own Chevy Question
Customer reply replied 1 year ago
No. How do I get behind the instrument panel?
Chevy Mechanic: EricFromCT, ASE Certified Technician replied 1 year ago
The instrument panel needs to be removed to replace the actuator. But you should be able to see it by using the diagram that was sent to you. You will not be able to remove it just to check it without removing the instrument panel.
Ask Your Own Chevy Question
Customer reply replied 1 year ago
Ok. Where are the screws that are holding the instrument panel intact?
Customer reply replied 1 year ago
I only see one at the lighter and two above the dash where speedometer & gauges are located
Chevy Mechanic: EricFromCT, ASE Certified Technician replied 1 year ago
It is much more involved then that. The entire dashboard has to come out. If equipped the center console needs to be removed. It is actually a big job that pays 8 hours to replace

Customer reply replied 1 year ago
I have the dash panel off that goes around speedometer and climate control box
Chevy Mechanic: EricFromCT, ASE Certified Technician replied 1 year ago
Ok The radio, instrument cluster, lower knee bolster, hvac control module, center console if equipped, the glove box needs to be removed, the steering column also needs to be lowered.

I have the service manual information on this, that I can convert to PDF format, if you would be interested in step-by-step instructions.
Ask Your Own Chevy Question
Customer reply replied 1 year ago
Yes, that would help greatly
Chevy Mechanic: EricFromCT, ASE Certified Technician replied 1 year ago
Ok. There is a 10 dollar charge from the website for the information to be gathered from GM and turned into pdf files, and sent to you through this chat. It is for unlimited pdf files. Are you fine with that?

I want to unplug and turn rotating screw on motors to close heat flappers and to open cold door flappers until I replace motors next weekend.
Customer reply replied 1 year ago
No, thanks. I don't want to be charged again until I absolutely need it for the next stages. Thx!
Chevy Mechanic: EricFromCT, ASE Certified Technician replied 1 year ago
Ok. SOunds good. Let me know.
Ask Your Own Chevy Question
Customer reply replied 1 year ago
Which motor on driver's side (from illustration) do I have to unplug and turn manually with a screwdriver, etc to turn flaps for cold air only? We can rule out #2 because I saw it spin as I changed settings from to defrost and back to upper level.
Customer reply replied 1 year ago
Motor =actuator
Customer reply replied 1 year ago
Hello?
Customer reply replied 1 year ago
#2 & #3 are working correctly. #1 and the one on passenger side are the ones that are not working. I turned the passenger's side w/screwdriver. I couldn't get to #1 on driver side. I have a visual and can touch it, but I can't turn rotator or unscrew all bolts to take out.
Chevy Mechanic: EricFromCT, ASE Certified Technician replied 1 year ago
Hi. Number 1 is the temp actuator. Is your vehicle equipped with dual temp control?
Ask Your Own Chevy Question
Customer reply replied 1 year ago
I figured out that #1 is the temp actuator for the left side and the one on the passenger's side is the temp acuator for that side. My problem is removing #1 for replacement or taking the front cover off to turn screw to allow cold air in.
Customer reply replied 1 year ago
I'll probably play around w/it again this weekend. I pretty much figured out most of this due to either the timing of response and/or the lack of illustration of what to remove without additional charges. Thanks for now.
Chevy Mechanic: EricFromCT, ASE Certified Technician replied 1 year ago
SOrry about the time delay but I am not online 24/7. The entire dash and then the dash carrier need to be removed before accessing te actuator. CLICK HERE for instrument panel removal. CLICK HERE for instrument panel carrier removal.
