pOSSSIBLE RELAY PROBLEM
The horn on your 99 Hyundai elantra works sometimes and sometimes it doesn't could it be a loose wire a blown fuse or should the horn be replaced?
When it does'nt work, put your finger on the horn relay located in the engine compartment fuse box. If you feel or hear a "clic", you're sure that the contact is good in the steering and the fuse is ok. You might have a relay or horn problem. (If the horn has a strange sound when it works, it should probably be replaced.)If you don't hear the "clic", you might have a relay problem or an open cicuit.
2000 grand am sometimes heater blower works sometimes not - any answers?
If a 2000 Grand Am sometimes has the heater blower working and sometimes it won't, the problem could be with the heater relay switch. The heater relay switch lets the heater blower know when to come on and when to go off. In most vehicles this switch is behind the glove compartment. This part sometimes gets corroded from condensation in this area.

It probably is wiring or relay.
89 Buick Century overheats when sitting in traffic Electric fan does not come on you replaced fan motor and still not coming on Is it the fan relay and where is it located?
Fan relay is located under the hood. There should be a box some where with fuses and relays in it. Check the fuse and relay. Sometimes tapping the relay works.
My rad fan only works the odd timesometime you have to hit the relay with the tip of your finger to get it to work put a new relay on but the same thing happens.?
It would probably be nice to know what we are working on. I had a similar problem on a 1994 ford escort, and it was actually the relay block where the relay plugs in that was faulty. Hope this helps.
How do I know if I have a bad Fuel pump or fuel relay?
Bypass the relay and if the pump works the relay is bad.
How do you know if you need to replace your fuel pump or your relay box on a 1987 190e 2.6?
You have to isolate the problem you are facing, if there is no fuel supply you can also have a blocked fuel filter. If you are sure of the problem, you can by-pass the relay and if the pump works then you need to replace the relay. To by-pass the relay you need a short length of 2.5mm cable to connect two (2) terminals. I shall get a diagram to indicate which terminals (in a couple of days. Regards Ehi
