Sometimes I get in the truck and crank it and the blower works ; sometimes it does not, usualyy when I need it the most!
I can hear the comrpessor cycling, I had a newe control unit put in a while back because I only had a high speed, now when it works I have all the speeds. I read somewhere that if you hear a ticking sound the blower is going out. I hate to buy another motor and install it and find it was not the issue. Could it be the resistor block or is that inside that control unit that was changed out. I checked the fan fuse, seems OK, swapped the fan relay with and identical one beside it, didnt seem to make a difference, Auto Zone says a loose connection and it may be, I have yet to pull the unti out and see, but I figured that you may have seen or dealt with this beforte, surely someone has. Please help. Dont mind buying the parts, just need to know which ones to buy ! Thanks to all. Dave.
