Blower issues!!!
Hello all,
I've been a member for a while, and haven't posted much....but i really need some help....I've done hours of searching the threads, and as a result, this is where i'm at.
1995 E320 sedan, 309k miles!! the blower is not working. what I've done:
1. checked all fuses, including strip fuse (which had a crack in it, but i bypassed with in-line 30amp)
2. took out/disassembled the CCU, didn't see any signs of arcing, etc. i actually plugged the board back in while apart, and touching my fingers on some points of the board made the aux fans come on, but that's it.
3. removed the 3-prong plug behind the brake booster and tested with volt meter. looking at the male part, affixed to the firewall i found the following:
a-left, closest to pass side-nada 0v
b-center-13-14v
c-right-9v, switched fan to low, got 1.2v
4. removed the blower motor, and bench tested with 12v. worked perfect.
so, guys, am i looking at a resistor, that goes under the blower motor? have i missed anything?
i'm halfway confident that the ccu might be ok, when i choose floor, defrost, etc i can hear all of the vac valves manipulating....
looking forward to your suggestions!! thanks in advance!!
