Cooling Problems

[BuickNut]

I have just recently had cooling problems, specifically fan not running. I have replaced the 3 relays with no luck. I have jumped the fan to see if it was the fan, it runs. I turn on the a/c and the fan does not come on. I have no check engine light on. Coolant sensor is next on my list. Does anyone have any idea?

Thanks for the help

I looked at the fuse block layout and I can not find a fuse for the fan.

There is a fan relay some place also could be bad.

Or the resistor at the fan could be bad also.

So. I would expect the wire or connector. checkout

Found It

It was the low speed side of the reastat on the fan. The wire was broken and it was not visible from the top.

Thanks all
