blower on AC/heater not working. dealer says it needs a $300 module & 3hrs. labor to do it

Go to several auto parts stores and describe what's going on There are computer sensors that works it Try asking at a parts store about a Blower Motor Relay 9 times out of 10 the part is less than $100 and you can replace it yourself or have someone show you how Big Car Dealership Garages are a rip off unless you have a new car under warranty or Grandpa has money to burn working on his 89 Caprice where a 1,200 repair bill is nothing to them Guess everyone is paying for the basic cable and bitter coffee lol

Thank you. Thought as much
