I recently had a trailer brake installed. All the lights were working for a short time. Now I don't have reversing lights or turn signals. No turn signal indicator on the dash either. HELP!!! I have checked and replaced any blown fuses.

If your talking about the turn/backup for the vehicle itself and not the trailer? Turn/back-up fuse 18 in fuse box, use a testlite, that circuit goes hot with the key on, if the circuit isn't hot, we'll have to backtrack the circuit. Maybe you need to talk to the people that wired the trailer brakes?

Fuse is new 20 amp. Also, having a problem finding the relay. Is it the same relay as the hazard flashers?

Even if the fuse is good, if there is no voltage on the circuit, the circuit is dead. The turn flasher shows to be located, driver side, under the dash. Sometimes these databases aren't correct about component locations?
