I need my blower working TODAY!! The weather is REALLY BAD!!!  What can I do to get it working until I can order my parts from The Electric Connection? 

The most common cause of no blower operation is a failed terminal on the black wire, position "E" of the seven wire connector. If you lost most or all speeds at one time this is likely to be your problem as well. It is easy to bypass in order to have some blower operation while you await your new parts from The Electric Connection. Locate the black wire at terminal "E" of the seven wire connector and cut it about two inches from the resistor. Locate the black wire that connects to the blower motor and cut this wire about two inches from the resistor also. Now join the black wire from the seven wire connector to the black wire that is still connected to the blower motor. Doing this simply reconnects the original ground supply to the blower motor but it does it outside of the resistor assembly. High or #5 speed should not work though beacuse the resistor's internal high blower relay no longer will have a ground supply. If the high speed happens to work it is only because the relay is stuck. If the relay is stuck, it may not turn off when the key is switched off, unless you tap on it or disconnect the wiring to the blower motor. Now just order your parts from The Electric Connection and you will soon have your system fully working to the original design.

Please provide  the application in the customer comments box at checkout, or Contact Us with the application. There are two different resistors available in this combo kit, and we must have this information before your order can be processed. Each combo is priced equally, but the application is important to ensure you receive the correct resistor. We need to know the year, make and model as well as the a/c type (manual or auto). We also need to know if your vehicle has bucket seats and a floor mounted center console.
