Intermittent ac issues

About 3 days I was pulling up to my house an my ac just quit blowing. Turned it off and then back on and it started working again.

Then today I get in my truck and turn the ac on and it doesn't blow at all. Until I get a mile down the road and retry it and it works fine and blows cold.

Anybody have any idea what's goin in? Any help is appreciated.

Sounds like your blower motor got a short. Might have to get a wiring schematic, and a volt meter and test your connections.

Where is the blower motor located? And the easiest way to get to it?
Is it possible it could just be the resistor.?

It's located in the back of glove box, you got to pull out the glove box, then there's going to be black insulation you pull that down then you should have a clear shot. I would actually test for continuity etc. with a volt meter before spending money on parts. It could be a simple fix like a bad ground or something. But when you open it up the resistor is going to be on right hand side of the heater box. Whatever you end up doing, you got to start someplace, Goodluck.

Does your cruise control work on an off too? And check your horn as well. Could be a module.
