hi, im new here but i post alot on smokionvette/corvette forum, any ways i have a 99 grand marquis and when im driving home one night the head lights just go out and i have to pull off and try to get them to come back on, also when i unlock my car with my keyfob the interior lights do not come on, any ideas?

 

This is (unfortunately) a very common issue. Your LCM (lighting control module) needs a new relay.

You have a few options; 1) buy a new LCM that costs about $460, 2) send your LCM to an eBay vendor for a new relay, or 3) follow this link and do it yourself:
