Toyota Corolla air conditioning control problem

Hello forum members! I have a 2008 Toyota Corolla diesel car, which has run 475,000 km. I'm struggling with a malfunctioning climate control unit. The air conditioning works sometimes and sometimes not, and two air conditioning mechanics haven't been able to find a solution yet. The compressor and radiator were replaced a year ago, but the problems unexpectedly appeared half a year later. Sometimes it works when starting, then stops while driving, or vice versa. The refrigerant is at the prescribed level, the compressor starts when switched on, but the lack of stable operation is still a headache. The mechanics suspect the climate control unit, but the tester doesn't read the climate control unit, only the engine control unit. Please, if anyone has a suggestion, share it with me. Thank you for your help! Gabor Boros.

A 2008 Toyota Corolla is experiencing intermittent air conditioning issues, with the climate control unit suspected as the cause. Despite the compressor and radiator being replaced, the problem persists, and mechanics have been unable to diagnose it due to the tester's inability to read the climate control unit. Suggested solutions include checking the electrical connections and wiring for any loose or corroded connections, as these could lead to inconsistent operation.

Check the climate control unit's electrical connections and wiring for any loose or corroded connections. A poor connection could cause intermittent operation. If you have a multimeter, you can test for continuity in the wiring. Let me know if this helps or if you have any further questions!
