Well I've got a question about the fan control switch? Is It normal for the connector for the fan control switch to be charred ..... I just took my dash out saturday night to replace my heater core and blower motor and when I pulled the connector loose from the fan motor switch it was completely charred.... Any help would be greatly appreciated..


It's very common. The best thing to do is replace it with a good used one. You can also remove the terminals from the connector and bend them so that they have better contact with the pins on the back of the switch. Loose contacts of course generate resistance which causes extreme heat and a possible fire.

ok thanks.. That's what I was thinking....taking the connectors out of their housing and covering them in shrink tubing so they can't touch themselves and just hooking them straight into the back of the switch.... One other thing I also seen where there were vacuum problems... Anyone know where I can get some of the small vinyl vacuum lines, Some of mine were extremely brittle, when I went under the hood to disconnect them, they just broke off...

Advance Auto Parts sells a rolled package of hard vacuum line.
