So i get a code 97/1497 on my hvac ,each start up i get the windshield defrost that flash for at least 15sec and once its operationnal it automaticly goes back to 25 degres(celsius,im in canada ) .
My air recirculation servo doesnt work at all, but the system is sending the signal , and ive testes it with a battery and it works .
So this code could be 2 thing , the ac harness(well i hope its not the main harness) or the ac amplifier , wich i tried another one and didnt change nothing .

Did someone ever change that harness , i was told i would have to remove the dash completly 🤷*♂️

If someone could help me out it would be appreciated alot .
If someone got the procedure to change it also

im pretty sure theres a way to not remove the dash completly ,well i hope

LOL you can take a stab at it here:

Then let me know if you have to remove the dash, or not.

Remove your glove box, and see if its doable. It looks like it runs just on the sides, and bottom of the housing. This is from a UK spec.

I was told its plugged to the immobilizer ? Is that possible or the guy was wrong ?

I think the immobilizer is not tied into it. It's just a harness. That would be a seperate system.

Nice pretty sure im gonna be able to pass it without removing the dash

The problem is that if i can prevent taking the dash off i will ,the dash is really fragile thats why i was wondering
