Summer will not crank, no click WINTER always starts

Asked by Mar 09, 2017 at 03:44 AM about the 2006 Cadillac DTS Performance FWD

Question type: Maintenance & Repair

    Lets try you that deal exclusively with Caddys

    Live in Minnesota

    In the SUMMER even a short drive where it doesn't get up to full operating temperature or even full up to it. I can get out to fuel up let's say. After this 15 minute shut down down....no start, no crank, no click even. Dashboard lights come on normally. Waiting, 15-20 minutes or so, zoom starts and everything works fine. I have started opening the hood while shopping in the hope it cools down faster. Reason below.

    In the WINTER, like right now I NEVER have the problem. Never.

New battery
Cables clean tight

    Garage wants to replace the starter....no I don't think so.
    What relay or ignition module could get so warm to intermittently fail when WARM but in COLD weather never is affected?

    I can't keep letting it run with doors locked in Summer to dodge the problem. So, guys, PLEASE help point me in the right direction. Battery and connections are fine.

    I can find nobody else with this issue, (Except accidentally in Caddy Catera forum..never found answer) so before I take it in and run up a big diagnostic bill, maybe someone here may help. Thanks in advance.

When I had my shop, I had one Cadillac that would do this after the intial start even if it only ran a few minutes, it would not crank until it was totally cold, and it was the starter, I put amp meters on the wiring and found that when it was in failure the starter drew nothing even thought the crank command was there from the key switch. So you might have your shop do that and see if it does the same thing. HTH
