My DRL's and blinkers wont work

Customer Question

hello - my DRL's and blinkers wont work
Submitted: 1 year ago.
Category: Toyota
Customer: replied 1 year ago.
One of my DRL's stopped working so I installed LED's. They didn't work, so I installed regular bulbs and they wont work either. I think perhaps a fuse blew or a relay.
I need help to fix ASAP, as I can't drive anywhere until it's fixed

my truck is a 2010 Toyota Tundra 5.7 liter

Hello. Welcome to Just Answer. Please allow me to assist you.Do you have a means to check power? 12 volt test light or DC volt meter? Please advise.

Customer: replied 1 year ago.
No I don't
Customer: replied 1 year ago.
I really think I blew a fuse. What ones should I check
Expert:  Toyota Service replied 1 year ago.

There are several fuses that power the headlamps. Since you do not have a test device. pull all of the fuses in the panel under the hood and examine each of them. Check for blown fuses. Then check the fuses in the panel under the dash on the left side. I do not think you have a relay issue, but I do think you have a blown fuse.

Ok..I will pull every fuse tomorrow morning and check

start with:

7.5 amp ECU B1

7.5 amp ACC

7.5 amo ECU-IG No 2

*****LOCK

15 amp TURN/HAZ

Expert:  Toyota Service replied 1 year ago.

4 HEAD fuses (2 lo and 2 hi)

Customer: replied 1 year ago.
Are all these located under hood or in cabin
Expert:  Toyota Service replied 1 year ago.

Ok. Let me know what you find. If all the fuses are good, we are going to need a test light.

Expert:  Toyota Service replied 1 year ago.

Both panels. That is why you need to check them all.

Customer: replied 1 year ago.
Ok and what would we be checking with the test light
Expert:  Toyota Service replied 1 year ago.

We would be looking to see if we have power in specific areas that would narrow down why your units do not work, and then work to find the cause
