AC started acting up. First it would only work on High. Then it started not turning on until I switched it back to off then on. Now it won't work on high/full.
The resistor affects the lower blower speed. I've figured where the location is for that. However it sounds like the relay is my problem. The only pic I can find is in a camaro from a few feet away. Described as between the radio and gauge cluster? Will both need to come out to find it?
Does anyone have a picture of the location of the relay in a firebird? Pic of the actual relay itself?
Finally anyone know the part number/price for the replacement.

I would check the I/P-1 40A maxifuse under the hood in junction box #2 first. It's only purpose is to protect the blower high speed circuit via the relay - all other blower speeds run through the dash HVAC fuse and the resistor pack, so if the fuse is blown, only the high blower speed would be affected.
The blower relay switches between full battery voltage for high speed and resistor reduced voltage for all other blower speeds. It is located under the dash on the instrument panel tie bar behind the knee panel. First, remove the plastic insulator panel under the steering column - it is held on by a couple of clips and a retaining tab at the floor mat. Then remove the four bolts holding the metal knee bolster panel and remove the panel being careful of the rear hatch release switch. The blower relay is held on to the tie bar by a couple of push pin retainers.
