2004 GMC envoy SLT. Blower motor would only run on high and stayed on even with key off. Changed resistor. Lasted 5 minutes and same issue. Changed blower motor and another new resistor. Now the blower works for like 30 seconds then shuts off for about 10 seconds then starts again. It does this on every setting except high. Dealer thinks digital control module or possibly a faulty resistor.
