Hi,

I see that you have replaced the relay, but the fan motors themselves go bad all the time
The first place to check is the 40 Amp fuse in the under hood power distribution center near the battery and be sure that it has not blown, it is fuse number 10
If it is good and the relay is good (some of the non factory replacement relays just do not work correctly) then when the Jeep has sat a while and is cool, start the Jeep and turn the A/C to max and watch the cooling fan, it should come on within a couple of minutes (provided that the A/C is in working condition) if it does not come on then the fan motor itself may be bad, if the A/C is not working you will have to allow the Jeep to reach around 210 to 220 for the fan to come on
Once you have the Jeep to the point that the fan should be running,if it is not running, unplug the fan motor connector on the passengers side of the fan shroud and check for power at the Dark green wire (should be battery voltage) and check for ground at the black wire with a pink tracer, if you have power and ground then the fan motor will need to be replaced .

Be very careful when doing this test as the Engine will be running and things will be moving, also the Radiator and surrounding items will get very hot
A note is that the fan may run but turn very slow and not draw enough air through the cooling module to keep the cruiser cool, if the fan does come on it should be spinning so fast that you can not see the blades, and if you put a couple pieces of paper across the grille it should pull them onto the grille and hold them in place


Thanks for contacting Fixya

2005 odyssey wiring diagram. Need to discover what 40A fuse BackUp Circuits is

What is the most popular item goes bad when throw code po882 on a 2006 pt cruiser non turbo 2.4??


This is a code for the 12v relay supply to the transmission. Check the fuses in the underhood relay/fuse box to make sure none are blown causing this code. If all are ok, it will take electrical diagnostics to isolate the source of the problem by checking wiring/control module etc.

Significant battery draw on my 2007 Honda Odyssey until I remove the fuse labeled "Back Up, ACC". 40A square type fuse. what circuit does this fuse protect?


Fuse #15 "BACK UP/ACC" (40 Amp) in the Underhood Fuse/Relay Box
protects the circuits leading to Fuse #7 "BACKUP" (7.5 Amp) in the Underhood
Fuse/Relay Box and also fuses (#5 "RADIO" (10 Amp), #6 "INTR LIGHT" (7.5 Amp),
#7 "BACK UP" (7.5 Amp), #8 "not used", and #9 "FR ACC SOCKET (10 Amp)
in the Driver's Fuse/Relay Box.
To further narrow down the source of your draw, pull each of these fuses one at a time.
No, that was not a "typo" There are 2 fuses marked "BACK UP" and are both 7.5 Amp and one is
in the Underhood Fuse/Relay Box and the other is in the Driver's Fuse/Relay Box. (I checked this 3 times just to make sure.)

No rad fan motor changed large relay under hood drivers side and 40 amp fuse is ok whats next


If no rad fan motor after the large relay and fuse, check the thermostat switch. It may be a bit messy but it's worthwhile connecting the fan motor straight to the battery terminals. This'll at least tell you that the fan is still operational.

Cooling fan quit running and i cant find relay


Relay may be ok, check the temperature sending unit that signals the relay to run the fan, it may just provide the ground for the cooling fan! Temperature sensor for the cooling fan circuit!

2001 PT Cruiser , have replaced the fan motor twice , a/c fine 2 weeks then blows it again ,something electrical I know ,but what ?


Check the voltage output of your car with the engine running. It should read 13 to 14 volts. only. Higher than this will cause damage to the fan motor, and other 12v gadgets in your car. Is this happening? If not, then, check the aircon evaporator for grounded wiring connections. This is the line from the fuse box terminal to the line going to the aircon. Grounded line can cause a lower voltage reaching your fan motor, forcing it to run undervoltage, overheating it. Send us your e-mail so we can give you further
assistance.

2006 trailblazer ls v6- A/C only blows on the floor & windshield, not from dashboard. A/C is cold, all fan speeds work. I replaced the relay & 40A fuse in the underhood fuse box, the fuses looked...


sounds like it might be a blend door motor, It is located on the drivers side up under the dash on the side of the heater box, try looking at it while turning the knobs on the dash and see if it is changing positions, if not than the blend door motor might be the problem

Heater stopped working today. Rear still working but not alot.


2005 Chrysler T&C Van. My front blower also stopped working overnight. Rear blower works fine. I swapped the 40A fuse in the underhood fuse box with the 40A fuse for the power seats since I don't have power seats. No help. I then swapped the front blower relay with the spare relay in the same box. No help. I'm wondering if there is a reset button for the blower and if so where it may be. Any hint or help with the blower would definiely be appreciated. Thanks
