Peugeot 206 blower motor issue

Interesting. Had a similar climate control issue with my old BMW 3 Series; turned out to be a faulty odor sensor. Ventilation system was acting up. Check the sensor connections and wiring harness first. Fuses related to the blower motor and climate control?

Fuses are fine. Any specific tools or methods you recommend for testing the sensor connections and wiring harness? Want to avoid causing more damage.

For the BMW, I used a multimeter to check the wire continuity and voltage at the sensor connector. If you're not familiar with a multimeter, a workshop might be best. If the sensor is faulty, it should cost about 95€ with installation. Peace of mind.

Appreciate the advice. I'll take it to a workshop to have the connections and sensor tested. Your BMW experience helped narrow down the causes.
