TRANSMISSION


Fuse # 20 or 21 gets power through ignition. This fuse controls PRNDL indicator, speedometer, tach, & will cause transmission to not shift gears correctly. Ours took off in 3rd gear when put in Overdrive & only ran in 3rd gear. If we tried to manually shift thru gears (auto trans), it had 1st, 3rd, reverse. No 2nd or over drive. Replaced ignition. Fixed problem. Root problem was Electric motor that engaged 4 wheel low side was bad. Every time we used 4 Low side it threw power surge through ignition & blew ignition out. Good Luck.

Horn not working


Check appropriate fuse isn't broken and from fuse work back along wire checking connections and insulation until you reach the horn. If you've not found a fault download user manual (for free). Ask advice at a Honda dealers or e-mail Honda directly.
Auto-electricians aren't cheap.
I'm not certain but I think youv'e gotta have working horn to pass MOT.
Good luck. Hope this helped.

We had the distribute replaced and now the brake


Sounds like a fuse, in the underhood fuse box, the brake lights & cruise are on the same 20 amp fuse. After replacing the fuse, check the brake lights first. Then see if the horn works, horns usually are the cause for a blown fuse, they short out.
