Default no high speed

1994 Manual Air controls.

I am sure there is prolly a post ont his already, I searched and looked through about 10 pages and gave up. so I appologive as I am sure this is a re-post.

I lost all speed about a month ago. I replaced the resistor pack and got 1st through 3rd speed. High speed still doens't work. I will assume this is a relay. If so, where is it? Is it interchangable with the low speed relay? I am almost certian I rememebr reading somewhere theere is a relay for speeds 1-3, and one for high. Thanks for all you help. I live in FL and damn these cars bake in the sun.

I'd be led to believe the manual from my 95 is close if not the same. It shows a blower relay and the high speed goes directly into it. The low, 2, and 3 speeds got into the resistor pack you've changed.

I see two possible areas for you to check. The blower relay when on high uses a 30a under hood fuse in the maxi fuse center. Fuse #3. Check the fuse, it'* either the fust or the relay. The blower relay is also in the maxifuse center. Book does not say which one.

But check that fuse first.

I have a post on this same thing (technically 2 posts). I just put a new one up, but didn't catch yours. Anyway, I'm having the same problem. I pulled out the #3 fuse, but that took ALL of my fan speeds away. I didn't have anything at all when I did that. So I went to the 6th one (in this pic Name:  DSC01054_edit.jpg

Size:  67.8 KB ), that is labeled "MAIN", and nothing changed. I haven't gotten an answer from anyone as to whether or not this is the fuse, so I'm skeptical. I still have the fuse sitting here in front of me since yesterday evening, and I've driven the car over 50 miles today with no problems. Hopefully someone can answer me soon so I can get it done before the baby gets here. The car just doesn't cool very well with the 3rd fan speed. Anyway, if that turns out to be the problem, I'll let you know. If someone answers, that is.

Guys...I thought I mentioned which one it might be. I'll have to look up wire colors in my 95 manual and hope they are the same for you. This is in case the relays have ever been out before and put back in the wrong order.

Bill,

Please let me know. I need to know what to replace so I can get the high speed working on mine, too. Like I said, the relay I removed hasn't made anything change that I've noticed, and randman1 described it as "MAIN" in an older post of mine. I don't know what he meant (main relay for EVERYTHING or what), but it'* made no changes to the vehicle. I'm hoping that'* the one I'm needing to change.

In lookin at the diagram that I had the other day it showed the high speed going straight to the blower where the other 3 speeds went through a resistor. Can you test at the blower to see if you have high speed power when you turn the switch?

I don't have a test light or a multimeter right now, unfortunately. :(

Ok.. got the 95 book open

Hi on the blower speed switch is direct to the blower relay. Pin 85 Orange wire
The relay also contains:
Pin 86 Blk
Pin 87 Red
Pin 30 Purple

It'* in the maxifuse center and the book says ID it by the wire color.
