The heater fan has lost low speeds / only high works could this be the switch or the fan its self?[/quote:07dd0c566b]

you need a speed control resister for the blower motor

The blower motor is fine other wise it won't be operating on high speed your culprit here 90% of the time is the blower motor resistor.

its not the real thing
but very close to it
2 year working on it and its not done yet
thank you!!

I used to owned a 68 with a 409 in it, also the 71 SS 454 like the pic. I modified the 68 from a 307 original engine to the 409. I bought both of them new. Brings back memories. 39yrs back-I should have kept it but the military keep moving me around.

wow! Nice car!! know what you mean though about the military my sister in the process of going from oklahoma to Alaska!! fun fun!!!!

I have same car. Had same thing happen to me. Easy fix, get resistor. it is up under the dash on the passenger side. It has 4 sets of resistance so the one or two that get the hottest burn out first. There is one screw that I couldn't get back in after replacement, but it works fine without it. That is a common problen so evryone has the part.

Jerry Z thanks for your reply, i think that i might have the same issue as you....could you tell me exactly under the dash board is that located. I cant find it and picture would be wonderful and a part number. Thanks a bunch.

I'm having the same issue, and was wondering if anyone could reply to the last post, with the pn and exact location.

thanks!
