QuestionI have a 1988 Cadillac Eldorado 2Dr Coupe. It has the 4.8 Ltr V-8 engine. It has 90,000 original miles and is in excellent original condition. It has always been regularly serviced, all electronics work perfectly, and up until this past year was a daily driver.
For the last year is has been started and driven approximately 2-3 times a month with no noticeable deficiencies. Occasionally the battery might be dead, but it took and held the charge like normal.
Problem: This past summer the air conditioner quit cooling, but discovered it had blown the fuse to the unit. Installing a new fuse generally resolved the problem, but last month it kept blowing fuses often and very quickly. It would cool for about 3-4 minutes before it would blow the fuse. There is no abnormal detectable noise coming from the compressor before, when the fuse blows, or after it blows.
The blower speed and the electronic climate control does not seem to be affected in any way. The heater function works as it should.
If this is a compressor problem, can it be rebuilt or freed up in some manner to stop blowing fuses and avoid the high cost of replacing with a new one?
Any information will be appreciated. If you need additional information, please let me know.
Thank You.
AnswerHello Larry
Thank you for your comprehensive detailing of the problem. It it very carefully written too, which is always appreciated.
We are a uk company so have no specialised knowledge of your vehicle; however, although I can't rule out a short in the compressor clutch coil, it is worth checking the following first.
Is the fuse capacity large enough.
Is there any water or damp in the fuse box.
Is there any corrosion around the earth terminal on the compressor
Does the system run for exactly the same amount of time prior to the fuse blowing, if so there may be a resistor or capacitor in the line breaking down
Hope this helps, compressors can be rebuilt, my feeling at the moment though is that the problem lies elsewhere
