Abt 3 months ago I had to repair the ac of our HighlanderN the ac repairer filled the gas and put oil in it saying the oil was to detect any leak in the condenser located in front of the car but unfortunately he didn't check thoroughly.
Fast forward to abt 3 months after the ac wasn't cooling againN took it to another ac person and a leak was detected on the condenser he said since the leak was inside we have to buy a new one and so we did, it was installed and the gas was topped, now the ac is working perfectly.
My point of confusion was when he said the heat in the engine must have caused the leak cos the fan speed was not sufficient to cool the condenser so he advised that the fan speed be increased, we called a nearby auto electician and he bridged the fan immediately he did I could hear the noise of the fan and to be fair to them the engine is now cooler as the bonet is not usually as hot as it used to get but I hate the sound of the fans I used to enjoy that super quiet engine but that groan of the fans can be so annoyin. Before I could sneak up on someone and the person won't notice until I blar the horn but now that fan sound just makes the engine noise noticeable.
My question is, was bridging the fans correct and if not what shld have been done. Can I reduce the noise of the fans?
Pls forgive me for the long post, it was just so I could state the issue clearly.
Thanks in advance for ur valuable contributions.

I would advice you to quickly go and revert the fan to it's original connection.

The days of that engine is numbered, if you continue to run that car with it. Also, get ready to be replacing that fan every now and then with that connection. They were not designed to spin constantly and on that noisy speed. You are simply killing the fan's motor and the bearing.

Your engine is suppose to run hot, for the engine to last long. So, your bonnet should feel warm and not cold.

Thanks Ikenna and Chiebube for ur responses. Pls is it possible that it was the heat frm the engine that led to the leaking condenser as the guy told me? The electrician also told me that the engine heat also led to a blown gasket on an avalon which uses same engine. One thing is sure though I'm returning the fan to its original connection. Thanks again guys.
