Hello! Well got the other engine put in my 97 Suburban and all is well except for the AC:grrrrrr: The previous owners stated when the burb was running they were not able to turn off the blower. It was stuck on high and wouldn't turn off. Well a little researching and I changed out the blower switch and the resistor. All is well with that, but also have another problem. When i push the A/C button to turn on the A/C I get nothing. The little orange light on the button will not light up and the compressor won't kick on. I did a few test and pulled the plug to the compressor and am not getting any power to the compressor when the button is pushed. Also pulled the relay and jumpered with a wire. I was able to get the clutch to kick in so I went out and purchased a new relay. Still nothing. The previous owners said the A/C worked and the blower was stuck on high. I'm thinking the button is bad because it wont light up or engage the compressor. What do you all think? Is there a way I can bypass the or test the switch? I also recharged the system thinking it was low on freon but had no luck.
