It's going to be a real issue if you can't use the aircon when in a
traffic jam on a hot day?

I once had a car in which it was not possible to turn the heater off
- we got by just fine with the windows open when needed, it never
seemed such a big issue that I had to bite the bullet and sort it out
(it was one of those jobs that you just knew you'd regret starting
before it was finished).
