In my previous post I went though the procedure to change out my Monte Carlo SS blower motor resistor Unfortunately that did not fix the issue and I moved on to the next component in the circuit. The blower motor relay. Again this is an inexpensive part and is worth the investment to repair my classic car.
I have to say that I now believe that Amazon carries everything or at least put you in contact with a vendor that has what you need.
Here is a link to the RY20 relay from Standard Motor Products that is an exact replacement to the existing relay. Under $14.00 at Amazon!
As you know I enjoy writing about my projects and things I work on in the hopes this will help someone else in the world. Recently I purchased a 1985 Chevrolet Monte Carlo SS and though its in great condition as with any 35 year old automobile there are lots of maintenance items that need looking after. While out for a cruise I noticed some issues with blower motor speed control and decided to give a go at repairing it.
Blower Motor Works, but only on high!
The blower motor works well, however it only runs on the highest setting. Any other speed other than high will cause the motor to shutoff. I had this same issue on a 1999 Pontiac Grand Prix GT and had determined the blower motor resistor to be the issue, so I figured I would replace the same in my 85 SS
