If fuse 38 is ok check the following.

Access the Central Electronic Module (CEM) located under the driver side of the dash. Remove shunt 20/27 (CSH4) and inspect terminals for burning and ensure they are making a good connection to the base.

Swap relay 2/62 with another similar relay. If the headlights now work properly, replace the relay.

Hello, my name is***** am a Volvo Master Technician. Have you had the vehicle scanned for codes using the Volvo VIDA interface? The high and low beams on the vehicle use the same bulb which has a ballast that fires it up. When you activate the high beams, there are motors in the lamp which changes the position of the bulb and angles them up. It sounds like you may possibly have a bad light switch module or headlamp control module. These systems are somewhat complicated with the Bi Xenon lamps and the voltage is very high so it makes it difficult to diagnose. Sometimes the best way to diagnose these systems is by substituting known good headlamps to verify it is not an issue with the small control module on the bottom of the lamp. Any trouble codes you have may be useful in determining the exact issue, thanks!
