I have a 2004 Mitsubishi endeavor.....And when the A/C is on i here and funny noise when I press on the gas petal. Does anyone no what this could be ?

the word funny sound is pretty ambiguous, what you call funny I might call something else,, if its a squeal your belt/s are probably loose or worn out or it could be a compressor going out, hard to say so if you posted up a clip of it that would help a ton,, at least a better description, but best would be a clip

I️ had to replace the fan under the glove box as condensate was leaking into the fan causing the noise before the fan went out. The fix is a drain dealers will put in costing $260. There is a diagram on the Internet if you search
