High beams not working

I have a 2019 sr5, Noticed this winter that my high beams would not come on until the truck warmed up then they worked fine, anyone else have issues like this

 

First step, check the bulbs and check the connectors at the back of the headlights

 

Welcome to the forum. Sounds like a relay problem to me.

 

Check the 20A Dimmer fuse for power.
Check the 10A Hi fuses for power with the headlight switch on Hi beam.

 

Have checked lights and fuses, only happens in cold weather, freezing and below, warm weather and after truck has warmed up they work fine

 

Need to be out there with a test light or voltmeter when its inoperative...then you can narrow it down to voltage or a ground issue

 

Check the fuses for POWER when this happens. Just pulling them and looking to see if they are good.

 

That is why is said to check the fuses in my post above. Checking those fuses will tell us what side of the relay we are working with.

 

This schematic shows the headlight circuit.

 

Warmed up in the engine compartment or in the cab? I ask because I have had electronic connections that didn't conduct until the small metal pins expanded with heat. This was a very hard problem to troubleshoot. It looks like the weather is warming up, so your problems maybe gone until next winter. Next winter try warming up the engine only with the cab heat off. This could possibly give some direction as to where the problem is occurring. Why did you wait until now (Summer) to ask??

 

Yes seems like a relay is sticking. They are inexpensive.

 

Out of curiosity, did you have auto high beams turned on?

 

Yes auto high is on
