This is the second post so the year and all that is more apparent.
Around 8 months ago my blower fan started intermittently blowing and eventually quit. The chain shop near my house told me no question it was the blower motor gone bad. Last night I replaced the blower motor (pretty cheap part) and still nothing. I can feel the engine change idle when I turn the cooler on but nothing blows. My regular mechanic told me he thought it was the resistor based on my description (though I had assumed with a resistor issue it would tend to blow on high speed but not low and this blows never). Does anyone have any ideas on what it could be? The diagnostic fee if it isn’t the resistor is $60 an hour so I have a feeling it will be cheaper to just swap out all the parts. I have a feeling it is the relay but I am worried that since I can tell the engine changes idle when I turn the AC on it isn’t, though I do not know for sure. Also if it is the relay there are three relays against the firewall and I am not sure which it is as the cases on them all appear to the untrained eye to be identical. Included is a picture. If you could tell me what you think the problem might be that would be great, and also let me know which relay is the blower relay.
