Re: 2003 chevy astro blower motor
Hi Old Master, Need help finding the other end of vacuum line on 2003 Astro. facing front end of vehicle, found line running from left, passenger side, to right over air intake going back & down toward driver side, rubber tube with broken smaller hard plastic tube inside just hanging. Where is the other end? can i get to it from the outside of vehicle or do i need to remove the doghouse? Thanks in advance for your assistance and photo if available.

Re: 2003 chevy astro blower motor
The image is actually a 1996 or newer 4.3L in a Blazer, so your 03 Astro 4.3L black plastic housing may look slightly different, but the function is the same.

Re: 2003 chevy astro blower motor
This is golfbum, I tried your fix for the now power on the high setting. I installed the
relay as described it did not work. I check the power on the two orange wires. The large on had battery voltage the small one did not. I check ohm on the small one it was about 5. Any ideas. golfbum |

Re: 2003 chevy astro blower motor
I know this is in response to a old thread, but my 2002 Safari van with rear air has this issue. And are very knowledgeable with this issue and how things really work
I have had to replace the resistor several times since I purchased with 5,000 miles, it now has 166,000. Each time, also had to replace the socket as the large orange socket was burnt. So if possible I would like to remove that problem. Does this relay bypass only the high fan? if no, is there a way to ONLY bypass the High? as that is the highest amp draw which causes burnt connections, especially when there is a grounding or motor failure problem. I would figure you disable the resistor completely, since you remove the 12v source (large Orange wire) in your relay application. unless it back feeds on the red wire from the fan. |

Re: 2003 chevy astro blower motor
The mod will bypass the OEM high speed blower relay.

Re: 2003 chevy astro blower motor
I have the same "high setting" issue with my A/C. We replaced the connector to the resistor because of all the burns we had seen on it. All wires soldered&heat shrinked and everything.
Also, replaced the blower motor and the fan resistor . Our mechanic had stated that there is no power going to the "thick" wire. Ive seen everyone say to check if theres power going to it and there is not. How do we even solve this issue without bypassing , or jerry rigging anything. I am not too good with mechanic work, nor electrical issues. But its really hot out now and our astro is our work horse and we need it fixed asap. Thanks |

Re: 2003 chevy astro blower motor
Very old thread.
Hi, I'm new to this forum and saw a post about what I'm working on, a 99 Astro with a blower motor problem where the high speed doesn't work and there's a burnt large power wire going to the resister 12 volts on the large wire to the resister relay 12 volts to the small orange wire I saw that someone here posted a work around where they were adding a relay to bypass the resister...But that doesn't make sense to me how it is wired. If you disable the resister, then you only have the high setting and none of the others. If I'm not missing something, wouldn't it be better to keep all the wires going to the resister relay except the large power wire and use it as a signal wire for the bigger relay and then use the red wire from the battery that was cut to the relay... That way you could keep all the speeds and be able to handle the larger load of the fan motor when it is on high. Please correct me if I am wrong, as I am looking for an alternative, but like I said I want the other speeds to work too... Last edited by CargoJoe; 07-30-2023 at 02:16 AM.

Re: 2003 chevy astro blower motor
Never mind, I wrote this late at night and realized what I want to do in this case won't work. Any other ideas using a relay though would be appreciated.
