89 blower problem

Well, I have an 89 Trofeo with a VIC and have a pretty serious problem. My blower doesn't turn on.

Orriginally, it would work when I turned the car on, but if I shut it off again, it wouldn't start back up for about 5-6 hours. So I swapped out the blower motor, and now it doesn't start at all. Going on the advice of someone else, I replaced the AC programmer, to no effect.

Recently, I pulled out my multimeter and started running some tests, there is power going to the fan, but only 1.62 volts, as apposed to the 14 it's supposed to have.

I really need to get this solved before winter, I don't want to be driving my El Camino through the snow.. Any help would be greatly appriciated.

Re: 89 blower problem

Alright... back to square one...

I pulled a replacement from a scrap yard and installed it, the power read at 14 volts for about 30 seconds, then went down to 1.52 again, it does this everytime I start the car... and the blower never turns on...

Re: 89 blower problem

A bad blower motor or poor grounds can cause this also.

Well, weather the motor works or not is up in the air, but even a good one won't run on the 1.52 volts that are getting to it...

Are there any specific spots I should check for grounding issues? or do I have to open up alllllll those plastic tubes and tear appart my dash?

Re: 89 blower problem

Check your BCM for codes. Sounds like there is another issue...

I had run a diagnostic along time ago... there was one code that came up, but I couldn't find anywhere to tell me what it was... GM wouldn't even help me...

I'll run it again and post it here tomorrow...

Re: 89 blower problem

Ok, here it is.

There were no ECM codes

But there were 2 B111 codes
B552 - History
C553 - Current

Re: 89 blower problem

DTC B111= High side temp sensor circuit problem (check the data)
DTC B552= Keep alive memory error (normal for batt disconnect)
DTC B553= No such code.

I would go after the high side temp sensor ckt. It might be keeping the system from functioning at all.

Hope this helps...

It is C553, not B553

And the B111 seemed to be a division of codes, not a code itself, it wasn't labeled like the other ones... of course, I don't know much about it, just using logic... (but what about this car is logical?)

But, what can I do about a the temp sensor? I have no idea where that is... much less it's function...

Re: 89 blower problem

Well, I just pulled the blower motor and hooked it up to my el camino, it started right away, so the motor is good.
