Hi,
My a/c was checked recently for not blowing cold air. Of course it goes out the first hot day of the season. Everything checked out OK at the mechanic but they said I needed a new ECU. Everything else works ok on the car except the cruise control went out last year.
Can an ECU be bad for just a few specific things like that? I thought if the computer went bad the car would just not run at all.
They quoted a high price [400] but I noticed that autozone has them for about 100. An ECU seems to be something thats easily replaceable by myself. I've replaced chips in my computer, so an ECU shouldn't be too bad. I read that you have to use the old PROM and put that in the new ECU module, does that sound correct? Just disconnect the negative battery cable before you start?
Thanks,
itchy
