I posted a question last week about my Subaru’s a/c. Now it’s become more complicated.
Brief recap: My a/c started blowing less cool air so they recharged the system and added a dye to see if it leaks. (The air flow was perfectly normal, just not the normal cold) Over the course of about 2.5 months it sometimes blew less cool and sometimes seemed fine. Finally it was only blowing warm. Last week my (good and honest) mechanic checked it out and it was working fine for him. He let the car heat up outside & it was still fine. He recharged the system and added dye again. He didn’t charge me for either re-charge. He’s been kind many times in the past, knowing I’m short on funds and have a serious illness.
New complication: Everything seemed fine until 2 days ago. While out doing errands, I got in the car and the fan wouldn’t blow at all. It had been working just fine, (a/c too) the whole day. A few minutes later I tried it again and it came on. Then went off. I left the fan switch on and as I was driving it blasted on. I took it to the mechanic right then, who said it’s the fan blower motor resistor, which would cost $200-something. He went to get the exact price and came back to say the tech note says when replacing the resistor that the blower motor must also be replaced, as the new resistor can ruin the old motor. The new total would be about $800.
He said he could try just replacing the resistor by disconnecting the battery and doing some other stuff to prevent an electrical discharge. (I don’t remember exactly how he put it–I’m sure you get the gist) But it was risky and he can’t guarantee it’ll work. I don’t doubt his honesty, but I know even the most well-intentioned person might not have the right answer.
This car is 13 years old. I’m in a pickle-- no way to buy a new one, no way to pay $800 for a repair and no way to live without a car or a/c!
- Does this make sense with the initial A/C problem or could there be additional problems with the A/C?
- Does it sound like a bad resistor, and if so, can it be safely replaced by itself?
- Any other advice welcome.
