Hey guys can anyone help? My blower motor went out in my 99 discoII, So I bought a new one, swapped it and still nothing, I checked the voltage and it is fine, as I hit the fan button the voltage increases and I took both blower motors and put them to a battery and they worked fine. now I am stumped can anyone help??

 

Did you check the relay for the blower?

 

A/C control unit, most likely.
Have you checked to see if you have power from the control unit to the blower?

 

i'm having a similar problem where as the blower only works when it wants to. I swapped out the motor, but that wasn't the culprit. No fuses are blown. Sometimes the cold air blows faintly from the vents. Just the other day, i pulled out the control unit to see if there was a loose connection, but after giggling things around, no difference. When the wife and i were out and about yesterday, the air just started working while driving around town, but chose to stop working after we shut the car off. I'm no mechanic, but it sounds like a bare wire somewhere making contact????? or the control unit itself?? But all the functions on the control unit work, dunno. Any thoughts?

 

I had the same problem with an intermittent working blower. My problem was fuse block related, like many others on here. The passenger fuse block itself goes bad internally, for the blower fuses (the rest of the fuses seem to work just fine). A new\used fuse block has typically fixed the problem for some.

In my case, I had problems with both of my fuse blocks. The harness connector on the engine bay fuse block was dead on the pin that sends power to the Brown w/ Pink stripe wire (power wire to the passenger fuse block blower fuse). This pin gets power from fuselink 4 on the engine fuse block. Fuselink 4 was good with power. You can read my post about my fix here:

I ran an individually fused wire direct from fuselink 4 to the blower wire on the back of the passenger fuse block (the wire leaving the fuse block to the blower, see picture in link for connector). I have rear air on mine and had to wire it the same way. Everything works perfectly now.

 

Hey, after reading through all the old posts in the forum I tried by passing that fuse block under the steering wheel. I put an inline 30AMP fuse from the brown?red wire to the brown/pink wire and now we are in business, I read that the fuse blocks go out and was really hard to wrap my head around considering that I was getting good voltage to the plug and even varied voltage as I switched through the fan speed positions. But when I put the test light to it and I as getting NO amp push to the fan motor, I started believing. But as I said she is working great now and I have super cold A/C, I couldn't have done it without the help of the forum and all the posts from the past. A big thanks to all those who posted and since I do have a discoII I know I will need your help again.
