Fuse in engine compartment tht is connected to a pink/blu wire keeps popping

could also have too small of a fuse in

Check the pink wire. It goes from the ignition switch to two circuits in the under-hood fuse box and the ignition coil. One circuit goes to ENG-1, ECM-1, IGN-E. The other circuit goes to GAUGES, FUSE 4, AIRBAG FUSE 10 and TURN/BU FUSE 16.

If all those fuses do not have power when the ignition switch is turned to start or run check the pink wire as it comes from the firewall connection. If you don't have power on the hood side, there may be a bad connection between the two halves of the connector.

If you do have power on the pink wire on the hood side of the firewall then you may have to check it between the coil to the firewall connector and underneath the under-hood fuse box.

I would use a tone tracer on the pink wire while the ignition switch is in the off position. (turning the switch off makes the wire only go in one direction, to the engine compartment) The tool sends a tone signal through the wire (in this case it would be hooked up to the pink wire) and has a receiver that lets you follow the tone in the wire without having to open the wire harness. You can just follow the wire harness and hear the tone signal. if there is a break in the wire or the connection is terminated somewhere in the circuit the tone will stop. Makes it a lot easier to trace a wire.

had the same problem. Trace pink wire in harness rubbing on dogbox frame in engine compartment.

I suggest that you start by checking the fuse labeled HVAC 30A in the engine compartment fuse box. If the fuse is good, then check the blower relay for functionality by listening for a click while an assistant switches the blower on and off. The relay should be in the engine compartment fuse/relay box. If the relay appears to be working then check the blower motor resistor unit. Using an ohmmeter test the resistance between the DK BLU wire terminal C, and the LT BLU wire terminal A the reading should be around .26 ohms. Between the LT BLU wire terminal A, and the TAN wire terminal C the reading should be 2.1 ohms. And between the BRN wire terminal B, and the TAN wire terminal C the reading should be .71 ohms. If the readings are significantly different then replace the resistor unit. The attached drawings show the possible locations of the resistor assembly. If all of these things check out then either the control switch, or wiring are faulty, or the blower motor is bad.

always install your remote starter module inside under the drivers dash, never in the engine compartment, your ignition wire is pink

OK here we go you will need a test light for the following tests, i will try to be as descriptive as possible so lets get started

fist start the engine and turn on the a/c that should command the fan on.
right front engine compartment next to the battery is the power distribution center pop off the top, ground your test light to the negative battery terminal and find fuse number 10 it is a 40 amp fuse check both sides of this fuse with your test light, if you have power on both sides of the fuse than we shall go further.

unplug the connector from the cooling fan, there should be two wires in the plug one is dark green and the other is black with a pink tracer, with your test lite grounded to the negative battery terminal check the dark green wire for power, if there is power there than move your test light ground clamp to the battery positive terminal and test the black wire for ground,
if testing the black wire made the test light shine than the ground circuit is good, if it did not than check you ground connection behind the right headlight.
when testing the dark green wire, if the dark green wire made the test light shine and the ground circuit is good than you simply have a bad coolant fan motor.

I suspect you were not getting power to the fan motor so you will need to take a look at the radiator fan relay, this is a special solid state relay mounted to the inside of radiator core support on the right side down behind the bumper.

here you will find a single plug with 4 wires in it

black = ground
dark blue / pink = relay controll from pcm
dark green = output to radiator cooling fan
gray = battery power from fuse # 10 in pdc

unplug the relay ground your test light to the battery negative terminal, with the engine running and a/c turned on check the gray wire the test light, it should turn on if not recheck fuses.

move your test light to the battery posistive terminal and test the dark blue / pink wire, if the test light turns on than you have a bad radiator fan relay, you can pick one up at your local parts store for about $85.00 just make sure you get a high quality one the cheap ones have a hard time with the amprege consumption of that fan.

good luck
