Outdoor ambient temperature sensor connector corroded
I bought a new sensor and when went to replace it, one of the pins was broke off in the connector and the connector is massively corroded. I was wondering if anyone knew what the part number is for the replacement connector?
Thanks!
Thanks!

I solved it. If anyone else gets this issue and needs to solve it go to NAPA and they will have the pigtail connector. Get a few weather proof butt connectors, existing wiring is about 18 gauge, pigtail is 16 gauge. Get some dielectric grease as well.
to remove sensor push up on the retainer from below to loosen it, open hood and reach down and pull it out. You can check it from there to see if just your sensor is bad or your connector is also corroded.
if you need to replace your sensor it’s easy to do from above. But if you need to replace the connector it’s easier to do from below the car, unless you take the hood off. I did it from below.
I removed the passenger side under car trim cover in the front underside, this has 5 10mm screw bolts to remove. Thus will give you some room to pull the harness a bit to give you more room to work.
I had to cut the tape holding the harness and wires together and pull them out so I could work with them
make note of which color wire goes in which side of the harness, the pigtail wires are both black. You want too stagger the cuts so that you can tape and bundle it back together. Pay attention to how you stagger them and do similar on the pigtails so you can keep the correct wires in the correct places. Put on the butt connectors and crimp one at a time. When done I found it easier to do the heat shrink with a lighter rather than a heat gun due to the lack of space.
then wrap it all with electrical tape, put some dielectric grease in the ambient temperature sensor and connect! Go back above the car and feed the splice back into the harness and tape. Reach down and snap the sensor in place and then drive your car and enjoy your hvac system working correctly!
total cost was 30-40 dollars. Time maybe 30 minutes to an hour depending on your experience confidence and how many issues you have working with little space. I had one butt connector just not hold onto the existing wiring and had to go out to get more.
overall not a big difficult project, just tight work space but definitely something a novice can do if you can cut/strip a wire!
