Cutlass Digi Climate Control Swap


Recommended Posts

Posted

This is for a '90 Cutlass. Firstly I need some help with the wiring. There are a few I'm unsure about.

 

 

C1 GREY

 

7 - DEF SOLENOID

8 - AC SOLENOID

9 - BI-LEV SOLENOID

10 - RECIRC. SOLENOID

11 - TEMP. VALVE CONTROL

12 - VF DIMMING - LED DIMMING

13 - DIM ENABLE - BACKLIGHT

14 - GOUND

15 - EMPTY

 

 

C2 WHITE

 

7 - TEMP. MONITOR FEEDBACK - TEMP VALVE MOTOR HARNESS ( LOCATION 10)

8 - EMPTY

9 - INSIDE TEMP. SENSOR

10 - Green/black - Guessing this is outside temp sensor input but unsure

11 - EMPTY

12 - REAR DEFROSTER

13 - AC HIGH PRESSURE SWITCH

14 - HEAT SOLENOID

15 - BLOWER INPUT - NEW FAN SPEED MODULE

 

 

C3 BLACK

 

7 - GROUND

8 - +12V

9 - ALDL INPUT

10 - dark green - not sure what this for

11 - ENG/MET INPUT

12 - IGN. +12V

13 - IN/OUT TEMP. SENSOR GROUND

14 - Purple/white - not sure what this is for

15 - BLOWER FEEDBACK - NEW FAN SPEED MODULE

 

Also the fan speed controler does it sit inside the airbox between the blower and firewall? Can its harness be taken in one piece or does it need to be wired in?

 

Does the evap tube on the inside temp sensor "have" to be hooked up ,or will it still work without it but just be a bit inaccurate?

 

Any description of the actual swap and everything that had to be done to make it work would help lots. Any help greatly appreciated, Thanks.

Yes I searched LOTS!

 

 

This is what I have so far:

how are you goning to bastardize that into a lumina? It uses temp sensors and all that crap that your car doesnt have...

Sounds like he is putting all that shit in his car. Personally I love that Lumina he has, and I wish I was a little more brave to try and acomplish what he has done.

Yeah seen that, thats where I got that wiring info. Doesn't list everything though c2-10,c3-10,c3-14

Posted

off the top of my head the ppl wire is for the rear defroster. The others I can check my book but that's sometime tomorrow as it's not in front of me.

yes, C2-10 is the 5v outside temp input.

 

C3-10 is the serial bus data line- to the steering wheel hvac controls

 

C3-14 is the rear defrost indicator light- input.

I'll be on that, except the dual-zone part. I really don't want to swap out the whole box-assembly under the dash.

Thought about it but it's too much work and would cost a lot more to do, as parts aren't readily available. So far I've invested $10 :D

I totally understand the swap you did....I would never take on doing the dual zone swap because all the work wouldn't be worth the end result, IMHO of course

I could definitely appreciate that swap. I have a wife that is always cold!

The thing about these cutlasses is they get ice cold if you have the manual climate control which is why i'm putting in the auto climate control.
