My heat and A/C fan hasn't worked on high for years. I understand that there are two relays near the blower motor; one that affects high and the other effecting the other speeds. Also, I see in my fuse panel two fuses for the blower and two other fuses for the rear window defogger. All fuses look good.
The blower stopped working a couple weeks ago and I guessed that the blower motor is dead, but I just realized I've also lost the rear defogger, so now I'm thinking it might be relays.
What say ye? Thanks.
