Ok here's the problem, my wife's 03 KJ has an intermittent loss of blower motor function regardless of switch position. I replaced the resistor block(2nd time now) - still nothing. I replaced the HVAC switch cluster and it worked for a bit but has now quit working again. There seems to be no correlation between hot/cold or any other link that would point to anything specific. I am guessing blower motor but I don't want to spend money I don't have to, thanks in advance for any help.
