i changed the radio when everything wired ( i used a wiring harness ) so all was just a plug in not disturbing any other wires. but now the climate control only shows three dashes and the blower cannot be turned off. with the wiring harness there was a conversion pig tail for the antenna. I'm suspecting some kind of ground problem . anyone have any suggestions.

Hello! Please add the year and trim level of your car. If you ad this to your profile (signature) it will show up automatically on each post. Having this helps folks to answer your questions correctly and faster. Thanks!

Hello! You're lucky in that 93 was one of two years that the climate control had self diagnostics. Please follow this (incredibly easy) procedure to get the diagnositc trouble code which is making your Climate Control display dashes. http://www.bonnevilleclub.com/forum/...e=article&k=87
If the code displayed is not listed in the article, I have the factory service manuals which have the complete listing.

Is the blower staying on even when the engine and ignition is off?

no it shuts off with the ignition . will try the dignostics tomorrow and post results

well tried the self diagnostic but will not come up to use apparently whatever is disabled also disabled it

problem solved tried to hook up a PAC SWX 1 for the stering wheel controls that didn't work anyway cut it out and ac works fine thanks for all the help
