Dear Gurus in the house,

My mechanic worked on my engine yesterday. He changed the plugs, engine oil, filter. He also changed many fuses after he complained that most of my fuses are bridged and proposed that the fuses be changed.

After all the routine maintenance, my radiator fans does not kick in when engine is hot and AC does not cool (It picks and stops). Engine is overheating for the very first time since I bought the car.

I have attached an image of my fuse box. I'll appreciate if you guys can please help me check if anything was missed out in the fuse box.

I had to run the car this morning without the AC on to avoid overheating again.

Thanks in advance

Go back to the mechanic for a recheck or look for another not nairaland.

Look for an electrician to remove the thermostat. That solves your problem. Thank me later sha

You don mess up BIG TIME... Why change fuse when it's working the mech don remove the fan fuse maybe the one he put is not working.. Try get your fuse back

First things first here.
Here are some questions for you:
1. has the radiator fans being working before now?
2. how did the mechanic know that the fuses were bridged(shorted)?

Was there any electrical glitches you were experiencing that led him to recommend replacing those fuses in the engine fuselage?

Here's what you'd do:
1. ask the mechanic to have a rechecked of all the fuses he put in there.
It might be that he has mistakenly caused the radiator fan fuse to be shorted mistakenly, thereby leading to an open circuit in the fan circuits.

2. Whilst trying to replaced e some of the fuses, he may have mistakenly caused one of the fan relays to shift from its location (this would happen, if the slot in which the relay fits into, is worn).
Ask him to properly try pushing in the relays in their slots with little effort.

3. Do not ever agree to anyone that tells you to remove your car's thermostat.
The thermostat jeeps your engine's operating temperature at the recommended threshold, in order to effect efficient operation of the engine, and the fluids in the car.


I hole this piece of suggestion helps you sort out the problem.

PS: My bet on this is that is either he mistakenly placed a low amperage fuse in there.
Ensure the recommended fuses were replaced.
Don't use a 7.5A fuse where a 20A fuse is required.
If you do, you'd get an open circuit problems (fan won't power up!).

Thank you very much. I have asked that he come back and recheck the fuselage for what has gone wrong since he is the one who worked on it.

And to your first question, the radiator fans have been working perfectly before the operation. There were some minor electrical glitches that prompted the replacement of some of the fuses like the side mirrors not working, the running light not coming on or misbehaving.
