Blower Switch for A/C

stearn · 01-09-2009, 02:25 PM

When returning to RV park from getting engine miss fixed I noticed the blower motor only worked on hi speed. I looked for a loose wire or blown fuse, found nothing. Could it be a bad switch??

As I recall, it works on low and high on the "cooling" setting only. It works ONLY on one speed on heat.

...edit ...I made an assumption that you are talking about the house ac/heat pump. If you are talking about the dash air, my answer does not apply.

I'm sorry I should have mentioned it is the dash a/c that isn't working on different speeds.

Hey stearn!
Would this thread help you?

Stearn, check the link that Ding-a-ling gave you. It is my saga of fixing my dash air. Hopefully it will be of assistance to you. There is another link you will find there to pictures of how mine was set up. Hope this helps you find the problem.

That is caused by the resistor failing. It is located under the hood on the heater/AC housing. It has a 4 pin connector and is held in place by 2 screws and sealed with silicone. Replace the resistor, and all will be fine.
