I have a 2008 Chevy Express 1500 Cargo Van and the AC will only blow on high after I hit a bump in the road otherwise it won't blow at all. Once I turn it off, it stops blowing again when started but after hitting a big bump it starts blowing again still only on high though. Could this be the fuse or is blower motor going?
The blower will only blow on High and will stop working after the car is turned off for a while, but if I shut off engine and turn it back on to ACC with all diagnostic lights on immediately after shutting off the engine the blower will continue to run. Then once the van is started the Air will still blow only on high. If I shut it off and leave it off and start the van later it will not blow until I hit a big bump in the road and it will start blowing again only on High though, is this the fuse? or is the blower motor going?
