95 850 Replaced A/C Relay - New One is BUZZING

Post by Ed3349 »

Replaced A/C relay behind glovebox today. Old one was bad and the plastic on it was actually melted. Think the previous owner put the wrong one in. Anyway, when I started the car and turned on the A/C, the new relay was buzzing like crazy. Anyone know what's causing this? I have no idea. Just want my A/C to work again. Any help from you seasoned veterans out there will be GREATLY appreciated! Thanks!

Sounds like you have a bad on - or it will be shortly. If the original one was melted you may have a power problem. If you can still read the numbers you may want to confirm it is the correct one.
