AoA All,
Our corolla 2006 model during driving is experiencing issues in A/C.
All of a sudden car A/C switches off. Current goes completely Zero and Yellow LED in A/C button gets off(Marking as 1 in below picture)
Then after some speed breaker or jerk or if u bang Dashboard then this Yellow LED in A/C button gets on and A/C starts working.
When my bro took car to A/C shop, they told A/C button is ok but Fan speed Regulator 1..2...3...4(Mentioned as 2 in below picture) is faulty, that is causing problem so they advised to install some "Relay" within Dashboard.
I am not satisfied with their diagnosis. Secondly, if i install relay, will it work only in single speed like at #4 or will also work slow like #1, 2 or 3 too?
Is there any other method to repair this Regulator know in case i do not want to install relay and prefer original like functionality
I am attaching one of corolla's interior to understand my situation:
