Question about 1990 Buick Century
My heater and ac fan only work on high i'm told it's the blower relays where are they located
They are located behind the right front headlights (passenger side). There is a bank of four relays mounted on a common holder. The four are for various purposes, one of which is to control the ac fan on the low settings. I got a bank of four used relays from and olds off of ebay. I plugged in the part number off the one I had into the search box to find it.
If a relay is bad, it will usually rattle.
