Hello,
First time posting here. Noticed my tail brake lights were not working so I replaced them with P21w bulbs. After replacing there's now glow plug light flashing on the dashboard and none of the brake lights work, not even the upper LED one. Cruise control is not working either.
I haven't replaced the fuse(s) yet but took a glance at some of them and everything seemed OK. Ran OBD test and got error code 16955 indicating fault brake switch. I replaced the brake light switch but that didn't clear the problem.
Could someone help me with this issue? What I'm thinking of trying next is:
1. Replace the fuse(s)
2. Replace the brake light switch again
3. Check the bulb connections and circuit for corrosion
4. have P21w5 bulbs also. Should I try those?
Is there anything else I should look for or try out? Which fuses should I replace? Does the glow plug light clear itself if and when the issue is sorted out?
Thanks!
