Re: 89 Camaro RS - No High Speed Blower
yeah i will probably check napa, they have the resistor (only place around) which i might replace anyway, and i'll probably have to do that maverick, thanks for all the help i really suck with electronics pretty bad, but hey i got my rear defrost working again, any idea as to why i only have one breaker in my fusebox when theres a place for two? because i dont have pwr windows?

well new relay is on the way, pretty sure its the relay as power goes to it but nothing after that has power, when i pushed the little copper strip inside it up to contact, the blower motor kicked right on so again pretty sure its the relay

Re: 89 Camaro RS - No High Speed Blower
I did this and thought there was a break in the orange wire as I has 12 volts at red and none at the orange wire.
If I understand correctly, there are 3 types of heating systems:
- manual
- electronic
- automatic
If you have the electronic version as my GTA does there are two relays for the blower motor. One for main power to the switch and the larger 5 pin relay for the two highest settings . My fan switch didn't light up at all. I was going to replace the orange wire and noticed there wasn't any power at the switch, so I traced it back to the relay. (if you shake them and hear any noise, they most likely need to be replaced)
Be careful when getting a replacement relay. There are a few different types. Mine had 3 pins on the bottom and one on the top left hand side.
When I went to pickup the 1st replacement it had 3 on the bottom and one on the top right hand side, which naturally wouldn't work.
This is the correct one with a pic:

They also list this one but can't confirm (no pic avail.)

FYI: the connectors under the hood were there and didn't have heat damage
Thanks for everyones input, hope this helps!
