I’ve got no blowers, the climate control unit responds to the fan speed, but nothing comes out through the dash, panel or floor. I ran computer code and got 01 back as a result. It’s had a new blower motor to replace the old one and tried a different climate control which was totally dead (didn’t help). I’m in the UK too so I can’t just go the scrap yard and pull one from a scrapper so any help would be appreciated to try a fix it!

Hi,

Based on what you indicated, the controller functions but the blower motor doesn't respond. If that is correct, we need to start by checking fuse 10 for power with the key in the run position.

Here is a link you may find helpful:

If that is good and has power to and from it, then I need you to go to the blower motor resister and check if power is present at the black wire with a tan tracer.

If that has power, then locate the black wire on the controller connector and see if it has continuity to ground. It should because the controller is working, but anything is possible.

I attached the OEM wiring schematic below or the circuit. It is a bit difficult to follow, so if you have questions, let me know.

Let me know what you find.

Take care,

Joe

Hi,

Sorry for the late reply, where is the blower motor resistor located at as I can’t seem to find it?

Hi,

It's under the hood and basically hidden. You will need to remove the cowl grill and the windshield washer reservoir to access it.

If you look below, I attached the directions which also show the location.

Let me know if this helps.

Take care,

Joe

Finally got to it after it rained for days on end and took the washer reservoir and it’s not there for some odd reason.

Hi,

I went back a year (1988) and forward a year (1990). The 1990 is the same as what I sent to you. The 1988 shows it behind the glove box area. See pic below. If your vehicle is an early production vehicle, there is a chance they followed and used the same design as the 1988.

Check that and let me know. You will need to remove the glove box to access what is shown in the picture.

Take care and let me know if you find it.

Do you know what I have to remove other than the glovebox to get to it? I’ve looked underneath the dash and wasn’t able to find it either.

Thanks again

Hi again,

After doing loads of research, if I’m correct the New Yorkers with the atc unit didn’t use a blower motor resistor but in fact used a power/vacuum module, if I am correct what does it look like exactly and how would I test if that is the problem?

Thanks again
Luke

If you have automatic climate control, they used an automatic temperature control module (ATC). It is part of the vacuum module and located at the lower portion (right side) of the dash panel. See pic below. Also, I attached the directions for removing and installing the component.

Let me know if this helps.

I’ve got it working! Ended up being a bad connection on the power/vacuum module what was causing it to not work.
Thanks for all your help, you’ve been really helpful, wouldn’t have got it working without your help.
Probably hear from me again when the next thing goes wrong, hahaha.
Thanks again.
