Classic car technician Steve has been resolving an issue with the air conditioning in our 1973 Jaguar E-Type Roadster Series 3.
After removing the dash, Steve was able to gain access to the a/c wiring and control switches. The fault was traced back to the a/c control variable resistor switch so this was taken apart, the contacts cleaned, and put back together.
Steve tested the air conditioning afterwards and everything was working as it should.
