Customer Question

Customer: My name is ***** *****. (1999 Chevy Blazer LT model) Seems as though no jobber nor Chevy dealer parts guy knows what I'm talking about. I need to replace the heater fan, that I can do has the regular 2-pin connection and right beside it is another separate single pin connector. I have the electronic climate control option in this Blazer and was wondering if that single pin had something to do with it? Nobody out there can find me a blower motor with the extra single pin connection. What is it and do I need it? And where the hell can I get a motor/fan just like it for replacement.
JA: Thanks. Can you give me any more details about your issue?
Customer: Not really, just need an answer about the 3rd pin I suppose.
JA: OK got it. Last thing — JustAnswer charges a fee (generally around $18) to post your type of question to Chevy Experts (you only pay if satisfied). There are a couple customers ahead of you. Are you willing to wait a bit?
Customer: yes
JA: OK. Now I'm going to take you to a page to place a secure deposit with JustAnswer. Don't worry, this chat is saved. After that, we will finish helping you.

What color is that single wire?

Customer: replied 1 year ago.
The wire is brown, perhaps 16 gauge and then feeds over to a small box that has ITT Automotive forged into it, located on the Hvac compartment housing only six inches to the right of the fan motor. Of course I have yet to cut away the protective sheet covering the motor compartment.

Hmmm,,,i'm not showing that wire either and have no idea of what it's for so i will opt out and see if one of the other guys has ever seen it. If someone can help you will get an email notice. Best wishes bud.
