Cooling fan sub harness
OK well during the rebuild of my G, the wiring harness for the fans ( and other bits ) was smashed.... So I have a bit of a *concern* and need help.
I got new ( er ) sub harnesses with my fan assy, I got chunks for the engine bay harness from another member here. and used that to " freshen " it all up.. But I remember something was a bit off ( like some colors didn't match )... The car doesn't overheat... BUT the A/C on REALLY hot days.. has a problem kicking on till I get moving... The shop manual ( EC-470~476 ) shows point to point wiring with no sub harness shown... So I'm looking for actual pictures for the 2 fan connectors and or wiring detail. If I remember correctly I had to guess on a couple of things down there... Now I know each fan has 2 speeds 1-2 are the power feeds ( blues & red ) 3-4 are the grounds...pin 3's are hard ground ( Black ) pin 4's are switched ( Yellow's ). The fan connector (tab) ( Twds firewall ) on Fan Assy 2 | 1 ------- 4 | 3 So there are a few conditional states... which are a bit confusing.. and I can see a potential of 1 fan being in low , when high is needed. So any additional info would be great~ Thanks Mike |

Hmmm this might
Fan connector 1: 1. Blue 2. light green 3. Yellow 4. Black Fan connector 2: 1: Blue/white 2. Red 3. Yellow/Red 4. Black |
I can't seem to locate the water temp sender for the ECM...
Shop manual states it's in the water piping twds the P/S rear of the engine ( 2 pin connector ) any help on a location?? Mike |
the temperature sensor is #4 in the diagram below (ignore the boxed items):

Ok I found this
On the pass side fan the Black & yellow are flipped.. and on both connectors the High & low speed are flipped CHHRRRIISSSTTTTTT So I have wonky fans and no PROPER depinning tool... the upshot is when I call for MAX COOLING it's there and durning low cooling 1 is on high and 1 is on low Mike |
OK
(tab) ( Twds firewall ) on Fan Assy 2 | 1 ( hot ) ------- 4 | 3 ( ground ) So conditions 1 ( power ) 4 ( ground ) runs ( low speed ) 2-3 runs ( low speed ) 1-3 runs ( low speed ) NOW 1-2 HOT 3-4 Ground Runs HIGHER speed ~ 200-300 rpm more Tested on bench W stock 03 Drivers side fan motor no blades... |

i gota stupid question fr u im rebuildin my g font end was all smashed in so i been workin on it for a while had to get new hood bumper headlights radiator and condenser also fans and shroud amongst alot of other things but im wrappin up the project and wonderin do the fans go tward the front of the car infront of radiator tward bumper or behind closer to engine? im lookin at service man and cant tell im shure id figure it out but if u tell me less work lol thanks
|
A/C condensor goes in front of the radiator ( twds grille )
fans go behind ( twds block ) |
ok thanks i got the radiator and condenser hooked up jus didnt kno where to mount the fans but toward the block makes sense i forgot from when i was tarin it down, what about ur ac did u bring it sum where assuming u had the condenser disconnected and had to have it refilled with freon n oil? my a/c system is dry i mean as far as freon n im shure i lost some of that a/c oil cus i replaced my condenser and the lines were unhooked for a lil while any input is much apricated, thanks bro are u almost complete in fixin ur car?
