Outside temperature sensor

Take it back to your Audi dealer pronto for a quick and thorough assessment.

most likely the outside temp sensor is faulty it is located in front behind the grill

it can be the sensor or the actual module that diisplays the temperature, does it display a temperature but it is incorrect? if that is the case it is the sensor, if no display then the module is defective

I would suspect that the connection to the outside temperature sensor is not good or the sensor itself is bad. Check the connection and clean and reattach as necessary. Otherwise replace the sensor. I think they're pretty reasonably priced.

The outside air temperature sensor for a 2000 Windstar is located under the front bumber on the passengers side. It is clearly visible if you lay down and look through the lower two air openings in the plastic bumper. It is the only electrical device in that area and it is made of black plastic.

you need to replace the ambient temperature sensor or do the math

The ambient air temperature sensor at the fron of the car has gone bad, a new one can be obtained from any GM dealer.

Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/sean_54c3a3dc48a7773c

there is a outside temperature sensor inside the lower front bumper
check wiring harness to sensor, or the sensor is defective

The sensor is located near the hood latch area in front of the radiator. If the temp is reading incorrectly, chances are it is defective. You can purchase a new one, they relativly inexpensive.
Disconnect the electrical connector then remove the sensor.
Good luck, let me know.

There are four sensors for ambient tempurature and they work in unison to provide information to the temp reading on the dash, the heater control head ( where to direct air, blending of warm/cold/outside/inside air flapper controls) depending on the ambient temp and the inside air temp sensor located just above the radio as well as the sun sensor on the top of the dash as well as the a/c compressor head.

When you start your car, the body control module takes the readings from all sensors, outside air temp located in front of the radiator, air temp sensor located in the airbox ( senses temp of air being drawn in from the outside into the air box), coolant temp, inside air temp sensor and the sun sensor on top of the dash (this is why it takes a few seconds for the climate control system to begine when you start the car). The intake air sensor is 1st priority, inside air second, coolant third, ambient 4th and sun 5th. For instance, if the sun sensor reads the sun is hot but the interior sensor reads cold, the inside akes priority. The goal is for the system to achieve a tempurature inside the car that matches the selected temp. It uses all of the sensors to set the system up to achieve that goal as quickly as possible.

Example; Its mid afternoon, sunny and 40 degrees outside adn your in stop and go traffic. The intake sensor reads 40 degrees, the outside sensor reads 60 degrees (heat from radiator...engine heat protrudes into cabin) and the sun sensor reads high (sun is strong). The system is set for 72. priority one sensor reads 40, inside sensor reads 65, ambient reads 60= system will blow hot air to the floor out put, dash outlets will lightly flow 65 degree air so the sun doesnt roast you yet your feet are cold(if it blew hot air from all outlets, your upper body would be hot but your legs/feet would be cold). as the interior sensor reaches desired temp, air will be distrubuted through thee dash, defrost and floor with the warmest air coming out the floor and defrost, coolest air out the dash vents. Its a complex system!

The two sensors that will screw the system up the most are the intake and interior sensors. the system will function reasonably well with just those two sensors though it wont blend air temps between outlets if the sun sensor isnt working. If the outside sensor fails, it simply uses the intake sensor, if the intake sensor fails it will rely on the front sensor. However, since the intake takes priority over the outside sensor, if the intake sensor sends incorrect resistance info rather than failing, it will take priority and cause the unit to malfunction such as in your case.

The intake air sensor can be changed from the outside with patience. If it where me, I would pay the two hrs labor and let the dealer do it right.
