I have located the fan switch sensor on the passenger side of the engine. I am trying to remove the connector to it, but it feels brittle and I don't wanna break it. How do I remove it with out breaking it?

92 RS 5L

 

carefully. use a pick to lift up on the tab, and small flat head and try to lift it out. soak it in pb blaster or wd-40 if you like. if it breaks, its breaks. buy a new plug or make one

 

Yeah, well I broke it trying to remove it. It was very brittle. I lifted the tab, but it broke like an egg shell. I taped the connecter to the wire and I managed to snap it on, and it works for now. The fan came on at about 225* like it is supposed to since I replaced the fan switch. I just don't trust it to last.

 

If anybody has a connector for the fan switch I could use one.

 

Just wanted to update my post. I purchased a connector from Napa for 13.00. I didn't know they had these. The GM parts counter didn't stock other connectors I was looking for. I needed a fan relay pigtail, and found one at a bone yard. GM didn't stock it.

 

yea, dealership wont have them. i needed a pigtail for my cold start sensor. advance auto actually had one in stock. i only had to metal pins on the wire. gm doesnt sell the pigtails, just the pins and the actual plastic plug. you need to assemble it. if its just one thing, its cheaper to just buy a pigtail

 

I need to replace the IAC connector on my RS, because it is very brittle, and some of the plastic has splintered off. NAPA wants 25.00 for one, but at least it's new. Maybe a discount parts store has them for less.

 

I noticed since I replaced the connector pigtail, the fan comes on before it reaches 220*. When I had it rigged, it came on at 225-230* This is good as far as I am concerned, but I am puzzled by this.

 

less resistance. the old wire was probably corroded, which would effectivly alter the temp that the fan would come. temp sensors vary in resistance by temperature. high resistance or an open circuit shows a low temp, which would make the fans come on at a higher engine temp

 

Yes, resistance is not recognized enough. For instance when copper starts to darken most guys don't put it together why their speakers crackle or don't work. The sensor wire looked pristine, but the sensor which is copper was dark. I bet is was a bad connection all along. The connector probably had cracks and let in moisture. I can't help but to wonder how many of these engines have overheated due to bad fan switches and relays. I never will be completely sold on electronic sh** for this reason.
