Went through car wash and outside temperature reading 82 degree farenheit - it's 110 outside here in Phoenix, AZ

Cant answer your question (Lincoln man myself), but I used to travel outside the US on business and developed several quick conversions to be able to relate to local conditions.

Quickie: to convert celcius to farenheit, multiply by 2 and add 30. Say 23° C then x 2 = 46 + 30 = 76° (approx).

This is a example if you were leaving on the 18th of this month also I listed the amenities and the total time of trip.

Replace the outside sensor. Its located in front of the ac condensor at the bottom.

the outside temperature sensor on vehicles takes the temperature of the air about 2-3 inches off the ground, that close to the ground it might be a couple degrees colder than the temperature on the thermometer you have mounted in the window of your house.

TO A DEGRESS THIS IS NORMAL, BUT IF IT GETS ONLY COOL WHILE STOPPED THEN THERE IS POSS A LOW CHARGE ISSUE, THE FASTER THE AC COMPRESSOR SPINS THECOLDER THE OUTLET TEMP, BUT IT SHOULD NEVER RISE ABOVE ABOUT 38-40 DEGREES FARENHEIT EVEN ON A 90 DEGREE DAY

the temp display can be switched between celsius and farenheit readings, since the car is from europe the default is celsius, The manual has instructions on changing back, You have to hold 2 buttons on the display per the manual.

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.

BLEND DOOR STUCK OR BROKEN. NEEDS TO REMOVE DASH AND HEATER/EVAP CORE BOS TO REPAIR REPLACE.

my 91 did the same thing an all i did was pull the thermostat out.it now runs at 210 degrees and i live in phoenix,az.115 degrees outside.
