A/C blower won't shut off car stalls
I have a 2010 Chevy HHR Lt AC blower will not shut off when I turn it to the off position car keeps stalling please help
UPDATE. The switch for heater/AC was burnt so got a new one. But the car keeps throwing P0107-P0106 I've replaced both MAF & MAP Sensors but the codes come back if I put my car in reverse I'm a 62 year old and I'm not sure what to check next I can't put it in the shop I live on a fixed income in California.

From obd-codes.com
P0106 could be caused by: Bad MAP sensor
Water/dirt intrusion affecting MAP sensor connector
Intermittent open in the reference, ground, or signal wire for the MAP sensor
Intermittent short in the reference, ground, or signal wire for the MAP sensor
Ground problem due to corrosion causing intermittent signal problem
A break in the flexible air intake duct between the MAF and the intake manifold
Bad PCM (do not assume the PCM is bad until you've exhausted all other possibilities)
