Can't get the lighter to work on my honda civic ex 2dr 97. don't have a manual so not sure which fuse to look at or relay. Can you help? no power at all.

if the fuse and relay is fine then check the horn itself. with someone pushing on the horn button check for power at the wire on the horn you should have power if not it could be a broken wire from the horn back to the relay. also check to make sure the horn has a good ground. if you do have power chances are the horn itself needs replacing. sometimes the horn pad goes bad, but that rarely happens.

manual if it in glove box should show where fuse are the fuse board cover normally has the fuses listed on it

Clean the horn terminals and make sure you have a good ground, fuse is good ?

the fan relay in the fuse/relay box under the hood. should be marked. pull it out and see if the fan stops (it should) when you reinstall it it should click, if it does the relay is good, and the Radiator Fan Control Module may be bad, its complicated to check, but if you think it needs one, I have a new one, HONDA part #37740-P0H-A02. verify the part number and see if it fits your car. (its under, near the glove box) I can fax a diagram to check it, if you want? email me, [email protected]

Yes there is a sensor and a fuse and a relay....You must frist check power at the fan...Red wire...when engine is hot

Hi:
I am reasonably sure that your horn relay is in the relay/ fuse box that is located beside your battery, on the rear passenger side , under the hood!

either on the firewall or it has a expansion valve inside the high pressure pipe ,bit old for the later i would have thought ,look under the bonnet and follow the pipes to the firewall and it should be their

cheack under the hood most cars have a relay box on the fenderwell with a acc fuse or relay in it

have your charging system checked, you may have a bad Altenator

fuse 27 under dash inside fuse panel, and it is a 10 amp
