03 possible blower problem..

[missc4]

I have an 03 bravada,,had it a year now and love love it.Never had a problem with it till now and I am not sure if it is a problem or what it is..
Ok here is what is going on,Just in the last few months my blower started shutting off.It is very random that it happens though.It has only happened like 3 pr 4 times in 3 or 4 months.From what I can remember if it decides it is going to do it,,then it will shut off with in 15 to 20 minutes after starting the olds.The blower will shut off for a few seconds to a minute and then come right back on. Any one else ever had this happen..
Also when i start the olds the blower does not come.After the olds has idled or been driven a few seconds to a minute or two the blower kicks on,,Is that normal for the bravada?

You will need to test it when it does it.
When it quits check for power to blower motor.
Does it do it on all speeds.
Also wiggle and check wiring and connectors and grounds.
Does it have auto ac controls?

The olds has climate control.
It will turn off at any speed and would be hard to test it because when it shuts off it is very random and only is off a few seconds to a minute.By the time it goes off and you think WTF it is back on..

Also do you know if it is normal for an Olds with climate control for the ac,or heat not to come on when the olds is started..Mine takes a few minutes or so before the blower kicks on.
